ElectroMagnetic InductionHard

Question

Some magnetic flux is changed in a coil of resistance 10 ohm. As a result an induced current is developed in it, which varies with time as shown in figure. The magnitude of change in flux through the coil in Webers is (Neglect self inductance of the coil)

Options

A.2
B.4
C.6
D.8

Solution

q =         ∴            ᐃφ = qR = area of it graph × R
