J. Phillips EECS 215 Capacitors Passive element that stores energy in electric field Cv q = Parallel plate capacitor d A C ε = dt dv C i = () 0 o 1 t v dt i C v t t + = For DC, capacitor looks like open circuit voltage on capacitor must be continuous (no abrupt change) What is the energy stored in a capacitor?
