Give a real-world function of a capacitor.

6*3 ohms - (3(1/6))^(-1) ohms = 18 ohms - 2 ohms 16 ohms

FULL BRIDGE RECTIFIER ... or pretty much any rectifier that turns AC into DC (e.g. switching power supplies).

Breakdown is a rapid increase in reverse current past the maximum voltage in reverse biased conditions
Looks good! Zener and Avalanche breakdown might also be good things to look up just in case.UTF-8 U+6211 U+662F wrote: Yep.

What is the RMS voltage of a sinusoidal wave alternating between 40 and -40 V? Why is this useful? How does this change if you consider a square wave which is 40 V half of the time and -40 V the other half?
. This number is the DC equivalent of an AC current. A square wave's RMS is 40 V.
