a)
Ns = no. of turns in the secondary coil
Np = no. of turns in the primary coil
Vs = voltage in the secondary coil
Vp = voltage in the primary coil
Is = current in the secondary coil
Ip = current in the primary coil
Ns / Np
= Vs / Vp
= 12000 / 125
= 96 (3 s.f)
b)
Power
= VI
= 12000 x (5.0 x 10^-3)
= 60 W
c)
Ip / Is = Vs / Vp
Ip
= Vs x Is / Vp
= 12000 x (5.0 x 10^-3) x 125
= 7500 A
