358641 A coil has an area of \(0.05\;{m^2}\) and it has 800 turns. It is placed perpendicularly in a magnetic field of strength \(4 \times {10^{ - 5}}\;Wb/{m^2}\), it is rotated through \(90^{\circ}\) in \(0.1\sec \). The average e.m.f. induced in the coil is:

358642 When rate of change of flux in a circuit is unity, the induced emf is equal to

358643 The magnetic flux linked with a coil at any instant ' \(t\) ' is given by \(\phi=5 t^{3}-100 t+300\), then e.m.f induced in the coil at \(t = 2\) second is:

358644 Statement A :
Faraday's laws are consequence of conservation of energy.
Statement B :
In a purely resistive ac circuit, the current and emf will be in phase.
