Answer 1

A transformer has 50 turns on its primary coil and 100 turns on its secondary coil. An a.c. voltage of 25.0 V is connected across the primary coil. What is the voltage across the secondary coil?

___________________________

Known :

Np = 50 turns

Ns = 100 turns

Vp = 25,0 V

Asked :

The voltage across the secondary coil ?

Solution :

Vp/Vs = Np/Ns

25,0/Vs = 50/100

1/Vs = 2/100

2 . Vs = 100

Vs = 50,0 V ✅
