Midge · Answer 1

V1 = 360 V

Explanation:

Applying,

Vs/Vp = Ns/Np ... Equation 1.

Vs = Voltage of the secondary coil, Vp = voltage of the primary coil, Ns = number of coils in the secondary winding, Np = number of coils in the primary winding

make Vp the subject of the equation

Vp = VsNp/Ns ... Equation 2

Given: Vs = 120 V, Np = 9 coils, Ns = 3 coils

Substitute into equation 2

Vp = 120 (9) / 3

Vp = 360 V.

Hence, V1 = 360 V
