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 ‘m’. If the temperature of the block is raised by ‘ΔT’. The potential difference V across the capacitance is
(a) √(2mCΔT/s)
(b) mCΔT/s
(c) msΔT/C
(d) √(2msΔT/C)
