hi guys! I've been having some trouble thinking about power in DC circuits. I've been guessing my way through my problems and have been correct most of the time, but i just wanted to know the following...
so if i have a dc circuit with a capacitor, resistor, inductor, and multiple voltage or current sources, how can i tell when each of the individual branches is supplying or consuming power? i know resistors always consume power, but I'm a little iffy on the inductors, capacitors, and sources. by default when i label my circuits, i use passive sign convention on the RLC (current goes from + voltage to - voltage) and i use active sign on the sources (i draw current from - voltage to + voltage).
thank you in advance!
