A 10V stroage battery of negligible internal resistance is connected across a `50Omega` resistor made of alloy manganin. How much heat energy is produced in the resistor in 1h? What is the source of this energy?

Text Solution

Verified by Experts

The correct Answer is:
7200
Here, E =10 V, t = 1h = 3600s. `R = 50 Omega`
Heat energy produced in the resistor,
i.e., `H = (E^(2)t)/R = ((10)^(2) xx 3600)/50 = 7200 J`
