Question

An ideal transformer has 5000 turns on its primary winding which is connected acriss a 240V. If the output terminals of the transformer is rated at 24V, 60W. What is the current in the primary circuit?

Answer 1

power is same for both primary and output (secondary) terminal.. which is 60 W in this case. we have, P=IV
here P= 60 W,
V (in primary terminal) = 240 V
so, by calculation I=0.25 A
