Energy Stored Capacitor
Easyphysics
Energy stored in capacitor is:
Select the correct option:
Solution
Incorrect! Answer:
(1/2)CV2
The work done to charge a capacitor is stored as electrostatic potential energy in the electric field between the plates.
- U=21CV2
- Substituting C=Q/V gives U=21QV
- Substituting V=Q/C gives U=2CQ2
