MCQ
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 ‘$\Delta T$’, the potential difference $‘V’$ across the capacitance is
- A$\frac{{ms\Delta T}}{C}$
- ✓$\sqrt {\frac{{2ms\Delta T}}{C}} $
- C$\sqrt {\frac{{2mC\Delta T}}{s}} $
- D$\frac{{mC\Delta T}}{s}$
