Derive an expression for electric energy consumed in a device in terms of $V, I$ and $t$ , where $V$ is the potential difference applied to it, $I$ is the current drawn by it and $t$ is the time for which current flows?

Open in App

Solution

Formula,

Electric energy consumed

$W = Q \times V$

$I = \frac{Q}{T}$

$= I \times T \times V$

$∴ W = I \times T \times V$
