That's probably the reason I consistently see ANSI style logic gate symbols in datasheets amd not the moronic "simple" rectangular representations that make circuits needlessly harder to read and skim at a glance

so you draw your resistors like a coil
would R drawn as a rectangle be more distinguishable yes or no?
for comparison. but when you start learning stuff more complex than highschool schematics which anon probably didn't you mostly use Z anyway and that's always a rectangle
The capacitor is two plates just the same as it's symbol. Electricity is not mechanical or hydraulic. Stop associating an independent physical phenomena with entirely different sets of physics. That is lazy thinking and leads to misconceptions.
The EU will make it a box soon, just like the resistor, all logic gates, and everything else.
Even the wires (since a wire has complex resistances and capacitances too).
There will be a bunch of cryptic symbols in each box to describe what it is (we can’t use the roman alphabet because it would offend some eu members, and reminds us of britain who left anyway)
>Even the wires (since a wire has complex resistances and capacitances too).
you draw a box, call it Z, and put some numbers on it to the best of your abilities. then you pretend the rest of the wire is ideal >(we can’t use the roman alphabet because it would offend some eu members, and reminds us of britain who left anyway)

The point is, we don’t put the resistances in boxes, just because someone puts any complicated thing they don’t understand in a box. You’d have these russian dolls of boxes in boxes until you follow the world standard.

Like the internet, all modern electronics were invented and developed in america. The new symbols were an attempt to nationalize it by politicians (who also developed the new “standards” in the first place) so the were illegitimate even before they were published.

euro standard clearly depicts a wirewound power resistor which comes in a square ceramic from the outside
while the american standard tries to depict the interior function of most resistors such as carbon foil or film resistors, which have a helical gap or wirewound resistors which have a wire going around a fiberglass core
both are fringe ways of depicting the resistor nowadays since the appearance of general resistors has changed a lot
for the ease of drawing by hand in the end both sides probably settled with their respective variant and anyone taking it serious enough should and does know both systems for depicting electronic components already by heart
The way we use it here is:
the american standard is used to show a non-complex impedance, meanwhile the european standard is used for the complex impedance, generally loads
IMO, it's a contextually based question. European standard implies a resistive load, whereas the American standard indicates a resistive property (inherent resistance of a wire).
With proper labelling in a schematic both would make sense and should be moron proof but personally I would prefer to see squiggly lines as purely resistive loads (wires, line filters) and boxes as loads that produce usable work (joules)
Both are shit. European random rectangle is not a quickly recognizable shape in a sea of ICs.
American squiggly line is even more moronic because it looks very similar to an inductor and can easily be confused as such on hand drawn schematics.
If I had to suggest a new shape it would be a stretched rhombus. Very distinct from any other thing you can find on schematics so it stands out.
The rectangles were invented later by IEC committees because a old carbon resistor physically looked like a rectangle when viewed from the side.
And, as BigClive said, “idiots were involved”
Initially, everyone shunned the new system, even EU based companies like Sinclair and Phillips. But then they made it law, and a BS (british standard).
If you use it, you also get a free gender re-assignment surgery.
i think the european one is better for real schematics since you can put the ref values inside the box. I do like the american one better though for things like theoretical circuit diagrams in text books. We also tend to use the european standard for impedances and the american standard for resistance in textbooks.
i know we use j instead of i because lower case i is used as the per-unit unit for current but i don't see how a V for voltage could lead to any confusion
can you give an example?
U is the symbol for "potential", as it is also used when integrating to find the potential energy of celestial masses and such.
In electricity it means potential difference, which is measured in Volts.
The problem is that Voltage is the unit for Electromotive force, so the symbol should really only be ξ.
Strange. I never knew there was a difference in standards. Equally strange is this is a schematic for a european appliance and I see the normal (to me) resistor symbol.

>Everyone who chooses the gay boring box is gay, therefore it's the weird lines.
Typical American bullshit. They'll defend any shit if they're not the winners.
> EU variable resistors r good
No, they’re fricking not. In fact, it proves the stupidity of the IEC “designers” and invalidates everything they put their name to, and everyone who tolerated their system.
Picrel from the standard. Note 2.1A says the descriptive text has to fit in the area of the asterisk. That’s not gonna happen cleanly.
These fricking idiots have never tried to make a schematic, nor seen one; and didn’t bother consulting with any smart people since they probably didn’t know any.
It’s just a way to sell more code books (changing random shit continually) to dumbasses who didn’t realize their tax money already paid for them.
the europoor standard represents what it physically looks like, the american standard represents what it actually does, resist flow. what takes more energy, a straight line or a zigzag to walk across? well, there you go
lines only represent connections, the length doesn't matter
this only increases the amount of people who confuse lines on a schematic with physical wires.
If I'm sketching a quick layout it I'll do the box because I have shite writing
But I expect to see the yank version normally
It's easy to give americans a hard time but this is one thing they got spot on.
whatever you say there is no denying that a rectangle is much easier to draw by hand compared to the squiggly line that always turns out sloppy and is easy to confuse with inductance.
So, you’re proposing an immediate ban on the letter shape ‘V’ because it is easily confused with the letter ‘U’ I think this is a ery good plan.
elcome to the EU.
Nonsense. Circuit diagrams are not something that need to be designed for literal monkeys. Even in 1948, we agreed that picrel was the best way to represent complex particle processes.
I’m sure some moron politician in the EU is working on nationalizing a moronic version for the illiterate.
American standard cause it actually shows what a resistor does (resist flow, which is shown by a squiggly line), European standard is moronic.

Here's a map of the EU; if you need a more visually accurate representation you're moronic.
That's perfectly adequate, thank you.
I've never seen someone get BTFO'd that hard. Thanks for the chuckle.
A very clear schematic for a collection of equal valued entities.
>equal valued
>American standard cause it actually shows what a resistor does
looks like an inductor. what a confusing symbol
It looks like a spring which is analogous to a capacitor.
The capacitor is two plates just the same as it's symbol. Electricity is not mechanical or hydraulic. Stop associating an independent physical phenomena with entirely different sets of physics. That is lazy thinking and leads to misconceptions.

If you're drawing by hand then just make a literal coil, no sense in having hard points on it.
a coil would be an inductor though

Came to post this. Rectangle is a combination of resistance, capacitance and inductance, a neat package if you will.
> resistance, capacitance, inductance
That’s a triangle.
Top is "two pin component" and only signifies a resistor if it has Rxxx or an ohm value next to it.
Bottom is the obvious correct choice.

European when using SPICE programs, American when drawing.
both, depending on my current mood

til Europeans use different symbols for resistors. 43yo and had no idea.
go back to le reddit
Have you lived under a rock for all your life?
The European one.
Also 'U' is the correct symbol for "voltage".
And "voltage" should be called electric tension.
never seen a U in my entire life and i've seen quite a bit of electrical bullshit. any particular reason?
>any particular reason?
to take away sovl
Because 'V' is already used for the unit, so there's less confusion.
i know we use j instead of i because lower case i is used as the per-unit unit for current but i don't see how a V for voltage could lead to any confusion
can you give an example?
If you have something like V = 10V instead of U = 10V.
And then you have V' = 2V.
Is V' two volts or two times V (=20V)?
U is the symbol for "potential", as it is also used when integrating to find the potential energy of celestial masses and such.
In electricity it means potential difference, which is measured in Volts.
The problem is that Voltage is the unit for Electromotive force, so the symbol should really only be ξ.

doesn't matter to me even if you mix them in the same schematic

>clarifies my point
Yeah, I draw the good and distinctive resistor symbol and not some Parkinson line.
Frick off with your virgin circuits. Bond graphs is the way to go.
C2 is missing from the circuit.....
C2 was eliminated for cost savings
That's Chinese supply chain for you
Euro resistors
US polarized capacitors
The block generally represents impedance, but the squiggly represents strictly real impedance.
We use both in the us.
The European standard looks better for variable resistors. The arrow pointing at the American zigzag symbol becomes messy and looks to disconnected.
> EU variable resistors r good

Bottom for real resistors, top for complex impedances.
I use the bottom one for simple resistance, and top when I start caring about complex components.
