Question 14

A source maintains a current I in a resistor of resistance R. If V is the potential difference across the resistor, the electrical energy dissipated in the resistor in time tis given by..........

Solution

The correct option is D.

We have, H = $$I^{2}Rt$$

By ohm’s law, R = $$\frac{V}{I}$$

H = $$I^{2}\times$$ $$\frac{V}{I}$$ $$\times$$ t = VIt
