A step-up transformer has an input voltage of 110 V (rms). There are 100 turns on the primary and 1500 on the secondary. What is the output voltage?
A) 1 600 V (max)
B) 1 650 V (rms)
C) 3 260 V (max)
D) 165 kV (rms)
E) 7.3 V (rms)

Question

Quizplus · Accepted Answer

The turns ratio is given by:
N2/N1 = V2/V1

Substituting the given values,
1500/100 = V2/110

Simplifying, we get
V2 = 1650 V (rms)

A Step-Up Transformer Has an Input Voltage of 110 V
