The formula for Joule’s heating effect is represented as __________. (In the options, H denotes the heat produced, I is the current flowing through the conductor, R is the resistance and t is the time period.)

Correct option is C

The correct answer is: (C) H = VIt

The formula H = VIt is one of the expressions for the Joule’s heating effect, where:

• H is the heat produced,
• V is the voltage,
• I is the current, and
• t is the time the current flows.

This formula is derived from the relationship between power and energy, where power $P$ is given by $P=VI$ (where $V$ is the voltage and $I$ is the current).

Over time $t$, the heat produced is the energy consumed, hence the formula for heat becomes $H=VIt$.
