How do resistor-capacitor circuits work?
I know this is a basic question, but it has bugged me, and is in two parts. The first: Are resistors like reduction valves for electricity? i.e. Do they simply absorb and dissipate excess electricity, or do they restrict its flow, as in making a large capacitor discharge its energy through a resistor to prolong output from the capacitor? Also, do capacitors store electricity until it is full, then release it, or is that only when they fail? Thanks!
