A rectangular coil of 20 turns and area of cross - section 25 sq. cm has a resistance of 100 Omega. If a magnetic field which is perpendicular to the plane of coil changes at a rate of 1000 tesla per second, the current in the coil is

Answer»

`1A`
50 A
0.5 A
`5A`

SOLUTION :Induced current, `i=(epsilon)/(R )=((NAdB)/(DT))/(R )`
`=(20xx(25xx10^(-4))xx100)/(100)=0.5A`
