The same current is passed through two wires of the same type for 1 minute and 5 minutes respectively. How many times the heat generated in the second wire will be the heat generated in the first wire?
Answer: If the current and the resistance of the conductor remain unchanged, the heat generated in the conductor is proportional to the flow time. Since the same current is being sent through two wires of the same type for 1 minute and 5 minutes respectively and the duration of the current in the second wire is 5 times that of the first wire, the heat generated in the second wire will be 5 times more than the heat generated in the first wire.
