The voltage across the input terminals of a transformer is 110 V. The primary has 50 loops and the secondary has 25 loops. The voltage the transformer puts out is
A) 25 V.
B) 110 V.
C) 55 V.
D) 220 V.
E) none of these

Question

Quizplus · Accepted Answer

The voltage output of a transformer is determined by the ratio of the number of loops in the secondary coil to the number of loops in the primary coil. Since the secondary has half the loops of the primary (25/50), the output voltage is half of the input voltage: 110 V / 2 = 55 V.
