Some magnetic flux is changed from a coil of resistance `10 Omega`. As a result, an induced current is developed it, which varies with time as shown in Fig. Find the magnitude of the change in flux through ythe coil in weber.

Text Solution

Verified by Experts

The correct Answer is:
2
`Deltaphi = R(Deltaq) = Rint idt`
=R[area under i-t graph]
`= (1)/(2)(4)(0.1)(10) =2 Wb`
