JEE MAIN - Physics (2021 - 31st August Evening Shift - No. 29)

A resistor dissipates 192 J of energy in 1s when a current of 4A is passed through it. Now, when the current is doubled, the amount of thermal energy dissipated in 5s in _________ J.
Answer
3840

Explanation

E = i2Rt

192 = 16 (R) (1)

R = 12$$\Omega$$

E1 = (8)2 (12) (5)

= 3840 J
