A 4 u F capacitor is charged to 400 volts and then its plates are joined through a resistance of 1 k W . The heat produced in the resistance is (a) 0.16 J (b) 1.28 J (b) 0.641 (d) 0.32 J

Question

Hrishant Goswami · Answer

(d) The energy stored in the capacitor This energy will be converted into heat in the resistor.

Rishi Sharma · Answer

Dear Student,
Please find below the solution to your problem.

The energy stored in the capacitor
= 0.5CV^2
= 0.5*4*10^-4*(400)^2
= 0.32 J
This energy will be converted into heat in the resistor.

Thanks and Regards
