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 to ∆T. Then the potential difference V across the capacitor is
- \(\sqrt{\frac{2 \mathrm{~m} \Delta \mathrm{TC}}{\mathrm{~s}}}\)
- \(\sqrt{\frac{2 \mathrm{~m} \Delta \mathrm{Ts}}{\mathrm{C}}}\)
- \(\sqrt{\frac{3 \mathrm{~m} \Delta \mathrm{TC}}{2 \mathrm{~s}}}\)
- \(\sqrt{\frac{\mathrm{m} \Delta \mathrm{TC}}{2 \mathrm{~s}}}\)
Answer
(B) 2 ~m Ts C
