(a) The voltage that is produced in the secondary circuit is 1,800 V.

(b) The current that flows in the secondary circuit is 1 A.

Voltage in the secondary coil

Np/Ns = Vp/Vs

where;

  • Np is number of turns in primary coil
  • Ns is number of turns in secondary coil
  • Vp is voltage in primary coil
  • Vs is voltage in secondary coil

100/1500 = 120/Vs

Vs = (120 x 1500)/100

Vs = 1,800 V

Current in the secondary coil

Is/Ip = Vp/Vs

where;

  • Is is secondary current
  • Ip is primary current

Is = (IpVp)/Vs

Is = (15 x 120)/1800

Is = 1 A

Thus, the voltage that is produced in the secondary circuit is 1,800 V.
