Question

Two identical capacitors have same capacitance C. One of them is charged to the potential V and other to the potential 2 V. The negative ends of both are connected together. When the positive ends are also joined together, the decrease in energy of the combined system is :

Accepted Answer

Correct answer: A. (a) V_C= q_ netC_ net= CV+2 CV2C V_C= 3 V2 Loss of energy = 12 CV^2+ 12C (2 V )^2- 122C ( 3 V2 )^2 = ( CV^24 )
