Question

The primary of a step-down transformer has 600 turns and is connected to a
120V ac line. If the secondary is to supply 5 volts at its terminal and electron
current of 3.5A, find the number of turns in the secondary and the electron
current in the primary?

Answer 1

Answer:

25 is the number of turns

Explanation:

n1/n2= v1/v2

600/x=120/5

5/x=1/5

x= 25

thats your answer
