Question

The number of turns in primary and secondary coils of a transformer are 100 and 20 respectively. If an alternating potential of $200 blank v o l t$ is applied to the primary, the induced potential in secondary will be

$10 V$
$40 V$
$1000 V$
$20,000 V$

The correct answer is: $40 blank V$

$fraction numerator E subscript p end subscript over denominator E subscript s end subscript end fraction equals fraction numerator N subscript p end subscript over denominator N subscript s end subscript end fraction rightwards double arrow fraction numerator 200 over denominator E subscript s end subscript end fraction equals fraction numerator 100 over denominator 20 end fraction rightwards double arrow E subscript s end subscript equals 40 blank V$
