Question

Energy stored in capacitor expression

Answer 1

Answer:

The energy stored on a capacitor can be calculated from the equivalent expressions: This energy is stored in the electric field. and will have stored energy E = x10^ J. From the definition of voltage as the energy per unit charge, one might expect that the energy stored on this ideal capacitor would be just QV.

Please mark as the brainliest.

Answer 2

Answer:

The energy stored on a capacitor can be calculated from the equivalent expressions:

     U=1/2×Q²/C =1/2QV      

           =1/2CV²

This energy is stored in the electric field.
