What size are they?

For shock value, would anyone like to share info on multicolored circuits? They are confusing the living daylights out of me, and I wanted to know if anyone knew if it is necessary knowledge for states or not. Haven't seen it yet.

Also, does anyone have a list of people who made major electronic breakthroughs/discoveries?

What do you mean multicolored circuits? Like the resistor color code?

in the rules it says any "basic" multimeter can be used. Are auto-ranging ones considered "basic"?

I believe so. There's a discussion about the letter of the rule and the intent of the rule earlier on this year, but I'm fairly certain auto ranging meters are basic.

Oops, I meant "multilooped. It autocorrected it 0.o


As in, circuits with multiple batteries. Can someone explain why the loop and current directions when using kirkhoffe's rules are arbitrary?

Because if you choose the direction to be wrong, you'll simply end up with a negative current. However, you should avoid kirchhoff's rules in circuit analysis as they result in horrendous systems of equations to solve, so instead learn the node voltage and mesh current analysis method, they reduce the number of equations and make your life easier. They are simply more simplified versions of kirchhoff's laws intended for analysis.

If your only issue is multiple batteries, I think its easier to do superposition with the batteries. But really just do whatever you're most comfortable with.
