An electric bulb of resistance $480\, \Omega$ is connected to $220$ volt main. Find the amount of electrical energy consumed in $10$ seconds.
An electric bulb of resistance $480\, \Omega$ is connected to $220$ volt main. Find the amount of electrical energy consumed in $10$ seconds.
Given $R =480 \Omega, V =220 V$ and
$t=10$ seconds
Electrical energy consumed
$=\frac{ V ^{2} t}{ R }=\frac{(220)^{2} \times 10}{480}=1008.3 J$
