Question

A current $I$ flow through resistance $\text{'}R\text{'}$ for the time $\text{'}t\text{'}$, the electric energy consumed by the resistance is

• A. $I\times R\times t$
• B. $I\times R^2\times t$
• C. $I^2\times R\times t$
• D. $\frac{I^2\times R}{t}$

Answer 1

The correct option is C

$I^2\times R\times t$

Electrical energy:

Electrical energy is the energy consumed or the amount of work done in a given amount of time.

Electric energy consumed is equal to the product of the square of current, resistance, and time.

$W=I^2\times R\times t$

The electrical energy spent when a current $\left(I\right)$ flow through resistance $\left(R\right)$ for time $\left(t\right)$ is $I^2\times R\times t$

Final answer: Hence option C is correct.
