a transformer changes 95 v acorss the primary to 875 V acorss the secondary. If the primmary coil has 450 turns how many turns does the seconday have g

The number of turns in the secondary coil is 4145 turns

Explanation:

Given;

the induced emf on the primary coil, = 95 V

the induced emf on the secondary coil, = 875 V

the number of turns in the primary coil, = 450 turns

the number of turns in the secondary coil, = ?

The number of turns in the secondary coil is calculated as;

Therefore, the number of turns in the secondary coil is 4145 turns.
