Alright, so, is my thinking correct in that: 1. Within a series circuit, a larger resistor will drain more power than a smaller resistor. 2. Within a parallel circuit, a smaller resistor will drain more power than a larger resistor. 3. Between two circuits, each with the same voltage source, the one with a smaller equivalent resistance will drain more power. I'm doing some MCAT prep and for some reason the power drain concept is difficult for me but I've think I've got the hang of it now. Any thoughts?
