In a transformer, the number of turns in primary coil and secondary coil are 5 and 4 respectively. If 240 V is applied on the primary coil, then the ratio of current in primary and secondary coil is

A

`4:5`

B

`5:4`

C

`5:10`

D

`8:12`

Text Solution

Verified by Experts

The correct Answer is:
A
In a transformer (No energy loss)
`V_S/V_P = N_S/N_P = I_P/I_S therefore I_P/I_S = N_S/N_P = 4/5`
