3.17 part 2

When the direction of magnetic field is perpendicular to the plane of the loop.

• The induced emf is zero

• The induced emf is maximum

• The induced emf is Half

As per flemming right hand rule

• The thumb indicates the direction of the motion of the conductor with respect to field.

• The thumb indicates the direction of induced current

• The thumb indicates the direction of flow of magnetic field.

the power delivered by a single-phase circuit is

• pulsating,

• circulating

• revolving

Which type of generators are useful for powering small appliances or for residential purpose.

• DC single phase generators

• AC single phase generators

• AC TWO phase generators

Windings of single phase alternators are connected in

• Series

• parallel

• series parallel

The poles of single phase alternators are of

• adjacent poles of opposite polarity

• adjacent poles of similar polarity

• Non adjacent poles of opposite polarity

The revolving armature alternator is found

• only in alternators of high power rating

• only in alternators of low power rating

• only in alternators of variable power rating
