Derive the expression for the energy stored in parallel plate capacitor. Hence obtain theexpression for energy density of electric field |
|
Answer» When a capacitor Is charged by a battery., it has to perform more and more,work done is stored as electric energy in capacitor,Therfore the work done is given as:dW = V dqAs we know that q =CVV = q/CW =∫dW =∫Vdq = ∫q/C dq= q^2/2C |
