Question

A transformer has 300,000 windings in its primary coil and uses 12,000V AC input. (4 points) How many windings would be needed to produce at output of 110V AC

Answer 1

Answer:

  2750

Explanation:

The number of windings and the voltage are proportional.

__

Let n represent the number of windings to produce 110 Vac. Then the proportion is ...

  n/110 = 300,000/12,000

  n = 110(300/12) = 2750 . . . . multiply by 110

2750 windings would be needed to produce 110 Vac at the output.
