Q. A transformer operates at $V_p = 6 \,kV$ on the primary side and supplies electric energy at $V_s = 220 \,V$ to a number of houses in a town. If the total power consumption of the town is $7.2\, kW$, the current (in amperes) in the primary is

Solution:

$P_{0}=P_{i}$
$\Rightarrow 7.2 kW =6 K V \times I$
or $I=1.2 A$
