Question

The primary winding of a 120 volt transformer has 200 turns. The secondary winding has 20 turns. What is the secondary winding voltage

Answer 1

Answer:

  12 volts

Explanation:

The voltage ratio is equal to the turns ratio.

  secondary/primary = 20/200 = v2/120

  v2 = 120(20/200) = 12

The secondary winding voltage is 12 volts.
