A rectangular coil of 25 turns, area of `25cm^(2)` and resistance of `4 ohm//turn` is placed perpendicular to a varying magnetic field, which changes at the rate of `500 T//s`. The induced current in the coil is

A

0.3125 A

B

31.25 A

C

4.25 A

D

9.8 A

Text Solution

The correct Answer is:
A
`I=(e)/(R)=(nAdB)/(Rdt)`
`=(25xx25xx10^(-4)xx500)/(4xx25)`
`=0.3125A`
