A current of 2.3 A flows through a small immersion heater with a resistance 50 ohms. Calculate the amount of energy dissipated in the same time

Dear Student,

​​​​​​Given,
current through the small immersion heater, $i=2.3A$
Resistance of the immersion heater, $R=50 \Omega$
Power dissipates or energy dissipated per sec. = $i^{2}R=(2.3^2)\times 50=264.5W or 264.5 Joules per second.$
So, in one second the amount of energy dissipated is 264.5 J.

In the question time is not given. Assuming it to be t sec. Then,
the amount of energy dissipated in every t sec = $264.5\times t J$

Regards,
