An electric motor takes 5 A from a 220 V.

solution:

Here, current, $\mathrm{I}=5 \mathrm{~A}$; potential difference, $\mathrm{V}=220 \mathrm{~V}$;

time, $\mathrm{t}=2 \mathrm{hr}=2 \times 60 \times 60=7200 \mathrm{~s}$

Power, $\mathrm{P}=\mathrm{V} \times \mathrm{I}=220 \times 5=1100 \mathrm{~W}$

Energy consumed, $\mathrm{H}=\mathrm{V} \times \mathrm{I} \times \mathrm{t}=220 \times 5 \times 7200=7.92 \times 10^{6} \mathrm{~J} .$
