Question

Paheli took a wire of length 10 cm. Boojho took a wire of 5 cm of the same material and thickness. Both of them connected the wires as shown in the circuit given in the following figure. The current flowing in both the circuits is the same.

1. Will the heat produced in both cases be equal? Explain.
2. Will the heat produced be the same if the wires taken by them are of equal lengths but of different thickness? Explain.

Answer 1

1. No, the amount of heat produced in both cases will not be equal. The amount of heat produced in a wire depends upon the length of the wire.
2. No, the amount of heat produced in the wire depends upon the thickness of the wire.
