Document Summary
Concepts " electric charges and forces similar to batteries ) electric field electric potential and potential energy capacitors . Store charge and electric energy charge can be released quickly since no chemical reactions are involved. Capacitors just need to be two conductors separated by an isolator ( air ) Capacitors can thus drive applications that require a lot of charge flowing in a short time flash laser. C when you close the switch you are discharging the voltage. Measure how much charge a capacitor can store for a given voltage. Pf - pet e does not depend on. V but only on the shape / material ( q and. C = e : for parallel plate cap . V : d =a . d c = Ai d can store you more charge by making the plate bigger. This is different from the kinetic energy that a particle acquires after passing through the potential between the two plates.
