Question

The primary winding of a transformer has 500 turns whereas its secondary has 5000 turns. The primary is connected to an A.C. supply 20 V, 50 Hz. The secondary will have an output of (A) 2 V, 50 Hz (B) 2 V, 5 Hz (C) 200 V, 50 Hz (D) 200 V, 500 Hz.

Turns on primary winding = 500; Turns on
secondary winding = 5000; Primary winding
voltage

(E_{p})

= 20 V and frequency = 50 Hz.

\frac{N _{s}}{N _{p}} = \frac{E _{s}}{E _{p}} or \frac{5000}{500} = \frac{E _{s}}{20}

or

E_{s} = \frac{5000 \times 20}{500} = 200 V

and frequency remains
the same. Therefore secondary winding will have
an output of 200 V, 50 Hz.

Q. The primary winding of a transformer has 500 turns whereas its secondary has 5000 turns. The primary is connected to an A.C. supply 20 V, 50 Hz. The secondary will have an output of

2 V, 50 Hz

2 V, 5 Hz

200 V, 50 Hz

200 V, 500 Hz.
