Rules for charge and voltage in parallel and series capacitors explained with equations and examples.

Transcript

okay in today's video I am going to go over the rules for parallel in series capacitors all right now I'm not going to give an explanation about what the rules and the equations are I'm just going to state them and kind of point out how they are opposites of each other okay I made videos for each of these we are going to go through the charge we ar...
