Question
An ideal transformer has 550 turns on the primary and 30 on the secondary. What is the maximum output p.d. if the maximum input voltage is 3300 V? And what maximum primary current is required if 11 A is drawn from the secondary (100% efficient)?
Correct Answer
Option A is the correct answer.
Detailed Explanation
Vs = Vp x (Ns/Np) = 3300 x (30/550) = 180 V. Ip = (Vs Is)/Vp = (180x11)/3300 = 0.6 A.
Hint
Vs = Vp x (Ns/Np) = 3300 x (30/550) = 180 V.
