Question

A step up transformer has 300 turns on its primary coil and 90,000 turns on its secondary coil. The potential difference of the generator to which the primary circuit is attached if 60 V. The efficiency of the transformer is 95%. What is the current in the primary circuit if the current in the secondary circuit is 0.5 A?​

Answer 1

Answer:

FOR STEP UP TRANSFORMER

Ns/ Np == Vs / Vp == Ip/ Is

Efficiency== power output// power input

Vs Is // Vp Ip

95/100 = 90,000 * 0.5 // 300 * Ip
