प्रश्न
At which position of the plane of the rotating coil with the direction of magnetic field, the e.m.f. induced in the coil is maximum?
उत्तर
We know that
`e=e_0 sin ωt`
where `e_0` is peak value for e to be maximum.
sin ωt = 1
ωt = sin-1 [1] = 90o
ωt = 90o
At 90o induced e.m.f. will be maximum
