Asked by Soniakumawat14 | 28 Feb, 2019, 02:52: PM
Expert Answer
According to Joule's law of heating, heat produced in the wire is directly proportional to the square of current, resistance of wire and time for which the current flows through the circuit. 
So, the heat produced depends upon:
Current in the wire
the resistance of the wire
time for which the current flows through the wire
