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

The number of turns in the secondary coil is 4145 turns

Step-by-step 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;

`(N_p)/(N_s) = (E_p)/(E_s)`

`N_s = (N_pE_s)/(E_p) \\\\N_s = (450*875)/(95) \\\\N_s = 4145 \ turns`

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