Allows you to put the value or number inside rather than underneath, etc.
PITA when all components etc become just a box like I've seen in some car schematics.

Those indians must have seen the zigzag symbol and thought that is how you make a variable resistor!

It's one of the standards. I try not to get too sucked into the fashion side of standards.

Not really no. Usually it means that its bollocks, and someone is trying to make it sound less bollocks.

Do galvanometers also meter out galvs? Seriously, voltage measuring is what they were used for.
I've seen old ones in zigzag form. The modern version is parallel wires. There is nothing in any way difficult about sliding a contact along a wire pegged to a board in a zigzag. It's trivial.
that's been done too. Early ones were simpler than that.
which so many mfrs don't altogether follow, but that's another story.

I know - I meant to say "used". But my Mullard "Transistor Circuits for the Experimenter" uses zig-zags!

Checks Bookshelf: 1969 publication still using zig-zags.

USA, Japan, and various other people. Its one of the main standards.

If you'd googled you'd have noticed those are used around the world for education & to a lesser extent calibration.
But I'm ceasing to care, it's not like you have much sensible to say about it.

that was when it all changed. I moved to Marconi's in 1969, and the standard was boxes. Woe betide you if you drew zigzags.

Still don;t see the zig-zag on the majority of these.
