In a coil of resistance, the induced current developed by changing magnetic flux through it, is shown in figure as a function of time. The magnitude of change in flux through the coil in Weber is
A) 8
B)2
C) 6
D)4
Correct Answer:
B
Solution :
The charge through the coil = area of current-time graph \[\because \] Change in flux
