AC Generator

In an ac generator, a rectangular coil of $100$turns each having area $14\times {10}^{-2} {\mathrm{m}}^2$ is rotated at $360 \mathrm{rev} {\min }^{-1}$about an axis perpendicular to a uniform magnetic field of magnitude$3.0 \mathrm{T}$ . The maximum value of the emf produced will be ______ $\mathrm{V}$ . [Take $\pi =\frac{22}{7}$ ]

In which positions of the coil the magnitude of induced emf in the coil of AC is (a) maximum and (b) minimum

An a.c. generator having a constant magnetic field is conneted to a resistive load. What will be the effect of doulbling the speed of rotation on:

(i) frequency of a.c.

(ii) generated e.m.f.

(iii) mechanical power required to rotate the generator ?

A $220 \mathrm{V}$ dc machine has an armature resistance of $1\mathrm{\Omega }$. If the full load current is $20 \mathrm{A}$, the difference in the induced voltages when the machine is running as a motor, and as a generator is
