Question

A capacitor of capacity 2muF is charged to 100 V. What is the heat generated when this capacitor is connected in parallel to n another capacitor of same capacity?

Answer 1

Answer:

The answer of this question is 1.25*10^9 C^2/F.

Answer 2

Heat generated for n capacitors in parallel will be , 0.01*n*mFV

•) Let, capacitance of the capacitor be C , heat energy generated be H and voltage applied be V.

•) Now , When n capacitors are in parallel then their total capacitance say C' will be :

C' = C + C + C +------------n

C' = nC

•) Now , we know ,

H = ½C*V^½

Here, V = 100V , C'= 2muF*n

Hence ,

H = ½*n*2muF*10000V

H = 10000*n*m*10^-6 FV

H = 0.01n*mFV
