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 figure. The current flowing in both the circuits is the same.

$(i)$. Will the heat produced in both the cases be equal? Explain.
$(ii)$. Will the heat produced be the same if the wires taken by them are of equal lengths but of different thickness? Explain."

$(i)$. 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.

$(ii)$. No, the amount of heat produced in the wire depends upon the thickness of the wire.
