A coil of cross sectional area 100 cm^(2...

A coil of cross sectional area 100 `cm^(2)` is placed in the magnetic field, which changes to `4xx10^(-2)Wb//cm^(2)` within 5s. What will be the current across `5Omega` resistance?

A

0.016 A

B

0.16 A

C

1.6 A

D

16.0 A

Text Solution

Verified by Experts

The correct Answer is:
B
`e=A(dB)/(dt)`
`=(100xx10^(-4)xx4xx10^(2))/(5)=0.8V`
`I=(e)/(R)=(0.8)/(5)=0.16A`
