The primary winding of a transfomer has 50 turns while its secondary has 500 turns. If the primary is connected to an a.c. supply of 220 V, 50 Hz, then the output at the secondaray will be

A

a.220V, 50Hz

B

b.2200V, 50Hz

C

c.2200V, 500Hz

D

d.22V, 5Hz

Text Solution

Verified by Experts

The correct Answer is:
B
`(E_S)/(E_P) = (n_s)/(n_p) = 500/50 = 10`
`:. E_(S) = 10 xx 220 = 2200 V` and frequency will be 50 Hz.
