ElectroMagnetic InductionHard
Question
In a coil of resistance of 10Ω, 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
Options
A.4
B.8
C.2
D.6
Solution
dφ = (iR) dt
ᐃφ =
ᐃφ = R × (area under i = t graph)
ᐃφ 10 ×
× 4 × 0.1ᐃφ = 2 weber
