A transformer has 90 turns on the primary coil and 175 turns on the secondary coil. If the input voltage is 120 VAC, the output voltage is
A) 62 VAC.
B) 92 VAC.
C) 230 VAC.
D) 180 VAC.

Question

Quizplus · Accepted Answer

The output voltage can be calculated using the transformer equation: $V_{out} = V_{in} \times \frac{N_{secondary}}{N_{primary}}$, where $V_{in}$ is the input voltage, $N_{secondary}$ and $N_{primary}$ are the number of turns on the secondary and primary coils, respectively. Substituting the given values: $V_{out} = 120 \times \frac{175}{90} = 233.33$ VAC, which is approximately 230 VAC.
