Answer:
No. of turns in secondary coil are 5.
Transformer Type: STEP DOWN TRANSFORMER
Explanation:
The relationship of the no. of turns in transformer secondary and primary coils with their voltages is known as the turn ration. The formula for turns ratio is as follows:
Np/Ns = Vp/Vs
where,
Np = No. of turns in primary coil = 40
Ns = No. of turns in secondary coil = ?
Vp = Voltage supplied to primary coil = 120 V
Vs = Voltage output of secondary coil = 15 V
Therefore,
40/Ns = 120 V/15 V
Ns = 40/8
<u>Ns = 5</u>
TYPE OF TRANSFORMER:
Since, this transformer decreases the voltage value at the output. Hence it is a <u>STEP DOWN TRANSFORMER.</u>
