Question

The plates of charged condenser are connected by a conducting wire. The quantity of heat produced in the wire is

• A. proportional to the capacity of the condenser.
• B. proportional to the square of the potential of the condenser.
• C. proportional to the length of wire
• D. independent of the resistance of the wire

Answer 1

Answer: (D)

independent of the resistance of the wire

The produced heat in wire, $H=I^{2}Rt=VIt$ where I is the through the wire for time t.
As $Q=CV$, so $H=\frac{Q}{C}It$. Therefore Heat is independent of resistance of wire.
Ans:$\left(D\right)$
