Question

A wire on the left with 9 coils and labeled primary winding. Another coil is near it with 3 coils labeled secondary winding V subscript 2 baseline equals 120. Use the values provided to calculate the initial voltage at the primary winding.


V1 = ? V

Answer 1

Answer:

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

Answer 2

Answer:

V1 = 360 V
