Energy Stored on a Capacitor
The energy stored on a capacitor can be expressed in terms of the work done by the battery. Voltage represents energy per unit charge, so the work to move a charge element dq from the negative plate to the positive plate is equal to V dq, where V is the voltage on the capacitor. The voltage V is proportional to the amount of charge which is ...

Energy of a capacitor (video) | Khan Academy
About. Transcript. Capacitors store energy as electrical potential. When charged, a capacitor''s energy is 1/2 Q times V, not Q times V, because charges drop through less voltage over time. The energy can also be expressed as 1/2 times capacitance times voltage squared. Remember, the voltage refers to the voltage across the capacitor, not ...
Capacitor charging and Energy storage
EC = CV2 2 E C = C V 2. The relationship between voltage, capacitance, and charge for a capacitor is. V = Q C V = Q C. Substituting this in the previous equation we obtain. EC = Q2 C E C = Q 2 2 C. The elastic potential energy stored in a spring that is compressed (or extended) a displacement of x x is given by. ES = kx2 2 E S = k x 2.
Energy storage in capacitors
Then it stops. Call this maximum voltage V. The average voltage across the capacitor whilst it''s being charged is (V/2), so the average power being delivered to it is I (V/2). It was charged for T seconds, so the energy stored in the capacitor is T I (V/2). The charge accumulated on the capacitor is Q = I T, so the total energy stored is Q (V/2).
