Heat developed = 2CV^2
Explanation:
Given: A capacitor of capacitance C is charged to V potential. The positive plate of it is connected to the negative terminal of V potential difference battery and vice versa.
As we are changing the polarity, the plates will get +Q and -Q charges respectively.
Total charge = Q- (-Q) = 2Q
W = q * ∆v
W = 2Q * V
We know that Q = CV, so substituting we get: W = 2 * CV * V = 2CV^2
