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

Question was already answered and there is a new question up but yes that is correct

FULL BRIDGE RECTIFIER ... or pretty much any rectifier that turns AC into DC (e.g. switching power supplies).
If the above answer is acceptable, what does it mean for breakdown to occur in a pn junction?

Yep.
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.

All right, great!

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?

You know, we don't need to know AC.
.  This number is the DC equivalent of an AC current.  A square wave's RMS is 40 V.

That's not true.
But yep, your turn.
