Question

The voltage leaving the secondary coil of a transformer is equal to 240 V. The secondary coil is wrapped 8 times around the core. The primary coil is wrapped 25 times around the core. What is the initial voltage at the primary coil?

Answer 1

750 0n edge ...

Step-by-step explanation:

Answer 2

The initial voltage at the primary= 750 V

Step-by-step explanation:

for a transformer

Es/ Ep= Ns/ Np

Es= secondary voltage= 240 V

Ep= primary voltage

Ns= number of turns in the secondary=8

Np= Number of turns in the primary=25

so 240/Ep=8/25

Ep=750 V
