Re: Circuit Lab B/C

What is the difference of total resistance of a circuit with 3 resistors of 6 ohms each arranged in a series vs parallel?
Series: 18 ohms, Parallel: 2 ohms

Re: Circuit Lab B/C

Well, it depends.
The resistance in series is 18 ohms (sum).  The resistance in parallel is 2 ohms ($\frac{1}{\Sigma\frac{1}{R}}$). The difference is 16 ohms.
When resistors are placed in series, the electrons have to go through multiple blockages to complete the circuit.  Thus, the total resistance is greater.  When resistors are placed in parallel, the electrons have multiple pathways, and thus they encounter less overall resistance.

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
