Question

22A current of 0.4A current flows through an electric bulb working at 230v.what is the Power of the bulb?

Answer 1

Given that ,

Current (I) = 0.4 Amp

Potential difference (V) = 230

We know that ,

$\sf \large \fbox{P = VI}$

Thus ,

P = 0.4 × 230

P = 92 watt

$\therefore \sf \underline{The \: electric \: power \: is \: 92 \: watt }$
