Question

A transformer assumed to be 100% efficient has 2500 turns in the primary and 50 turns in the secondary. What is the value of the primary voltage required to produce 4.4 V at the secondary?
Options
A 110 V
B 160 V
C 180 V
D 220 V
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

Vp/Vs = Np/Ns => Vp = Vs x (Np/Ns) = 4.4 x (2500/50) = 4.4 x 50 = 220 V.

Hint

Vp/Vs = Np/Ns => Vp = Vs x (Np/Ns) = 4.4 x (2500/50) = 4.4 x 50 = 220 V.
