Question

During the charging of a storage battery, the current I is 20 A and the voltage E is 12.8 V. The rate of heat transfer from the battery is 16 W. At what rate is the internal energy increasing?

Answer 1

Answer:

at 16 Watt

Explanation:

Here, Voltage, V= 12.8 V

          Current, I = 20 A

          Power, P=?

we know,

power = V × I = 12.8 × 20 = 256 W

The rate of heat transfer from battery is 16 W.

So, the internal energy increasing at the rate of 256÷16=16 W
