Question
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 ′m′. If the temperature of the block is raised by ′ᐃT′. The potential difference V across the capacitance is
Options
A.
B.
C.
D.
Solution
Dimensionally only 4th option is correct.
Approach should be energy balance 1/2CV2 = msᐃT
