In a transformer the transformation ratio is 0.3. If 220 V ac is fed to the primary, then the voltage across the secondary is

A

44 V

B

55 V

C

60 V

D

66 V

Text Solution

Verified by Experts

The correct Answer is:
D

Here, Transformation ratio, k = 0.3
As, `k=(N_(s))/(N_(p))=(V_(s))/(V_(p)) therefore V_(s) = k V_(p)=0.3xx220=66 V`.
