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 'DeltaT', the potential difference 'V' across the capacitance is

A

(a) `(mCDeltaT)/(s)`

B

(b) `sqrt((2mCDeltaT)/(s))`

C

(c) `sqrt((2msDeltaT)/(C))`

D

(d) `(msDeltaT)/(C)`

Text Solution

Verified by Experts

The correct Answer is:
C
Applying conservation of energy.
`1/2CV^2=m.s DeltaT`, `V=sqrt((2m.sDeltaT)/C)`
