PHY 184 Week 5 Notes-Capacitors 9/27-9/30 Capacitors o Device that can store energy Many different uses o Camera Flash o Touch Screens Essential in Electronics Capacitor consist of two separated conductors with an insulating layer o Can be rolled up with another insulator to increase the surface and storage A simple geometry of a capacitor each with area A and distance d in a vacuum with charge on one plate of +q and a charge on the other of -q The surface of the conductor is an equipotential surface o Equipotential lines are close to each other near the plate and far away outside of the plates Electric field lines are perpendicular to equipotential lines o Almost uniform between the plates o Far from the plates
