3 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 14.4. 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 10 cm 5 cm A B​
