An ideal transformer has primary and secondary coils of 200 turn and 40 turns respectively. If the current in the primary coil is 3A. Then the value of current in the secondary coil wil be

A

a.`10A`

B

b.15A

C

c.1.5 A

D

d.`5A`

Text Solution

Verified by Experts

The correct Answer is:
B
`(I_s)/(I_p) = (n_p)/(n_s) :. I_(s) = 200/40 :. I_(s) = 15 A`
