Question

A current of 5 Ampere is passed through the conductor of 12ohms for 2 minutes Calculate the amount of heat produced

Answer 1

Answer:

Given:

Current = 5A

Resistance = 12Ω

Time = 2 min = 120 sec

To find: Heat

Formula: H = $I^{2}$RT

Solution: H = 5 x 5 x 12 x 120

               H = 54000 J
