The electrical energy stored in a capacitor is given by E = (1/2)CV^2

V= potential difference across the capacitor

C= the capicatance of the capacitor in units of farads

a) C^2/J

b) V/C

c) J/C^2

d) C^2/V

The energy stored in a capacitor can be expressed in three ways: Ecap=QV2=CV22=Q22C E cap = QV 2 = CV 2 2 = Q 2 2 C , where Q is the charge, V is the voltage, and C is the capacitance of the capacitor. The energy is in joules when the charge is in coulombs, voltage is in volts, and capacitance is in farads.
