Question

How does the armature coil move during the stated working of an a.c. generator?

विकल्प

• It rotates in a uniform magnetic field \[B\] with constant angular speed \[\omega\]

• It rotates with zero angular speed

• It moves only when the magnetic flux is constant

• It remains stationary in a uniform magnetic field \[B\]

Answer 1

The armature coil rotates in a uniform magnetic field \[B\]. For the stated derivation, its angular speed \[\omega\] is constant.
