Question

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

Answer 1

Answer:

The number of turns in the secondary coil is 4145 turns

Explanation:

Given;

the induced emf on the primary coil, $E_p$ = 95 V

the induced emf on the secondary coil, $E_s$ = 875 V

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

the number of turns in the secondary coil, $N_s$ = ?

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

$\frac{N_p}{N_s} = \frac{E_p}{E_s}$

$N_s = \frac{N_pE_s}{E_p} \\\\N_s = \frac{450*875}{95} \\\\N_s = 4145 \ turns$

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