Questions
A fully charged capacitor has a capacitance C. It is discharged through a small coil of resistance wire embedded in a thermally insulated block of specific heat capacity s and mass n. If the temperature of the block is raised by T, the potential difference V across the capacitor is
detailed solution
Correct option is B
The energy stored in the capacitor =12CV2This energy is used in increasing the temperature of the block by ∆T. Therefore,12CV2=msΔTV=2msΔTC1/2Talk to our academic expert!
