Question:medium
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 by the town is \(7.2\) kW, the current (in ampere) in the primary is
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 by the town is \(7.2\) kW, the current (in ampere) in the primary is
Show Hint
For an ideal transformer:
\[
V_pI_p=V_sI_s
\]
So power is conserved.
