The process by which an emf induced in a DC generator is known as
method.
(2) static (ए) dynamic

(©) mutual induction (2) self induction

Testing a wiring installation for insulation resistance is to ensure that :
(ക) ചി conductors have high ohmic value in the circuit
(B) all outlet points are earthed properly to ground
(C) leakage current beyond the stipulated value does not flow to earth
(D) live and neutral conductors in the installation are continuous

In this wiring, to operate 3 lamps in all we require 6 two way switches :
(ಗ) corridor wiring (ए) godown wiring
(0 tunnel wiring (D) hostel wiring

Fleming's Right hand rule is used to identify the :
(A) direction of current in a motor (ए) direction of rotation in a generator
(C) direction of rotation in a motor (D) direction of induced emf

To get sinusoidal wave shape of an alternating current :
(4) एम] should rotate under uniform field
‏ری‎ coil should rotate under more number of poles
(0) two slip rings must be used
(0) armature should have more number of coils

n a DC machine, the conductors லீ the armature windings are soldered to commutator at
the :

(ಗ) segment internally (2) ಜಾ

(©) segments directly (D) brushes

The inter poles are connected in a de genérator :
(4) in series with armature and of same polarity ahead of approaching pole
(B) in series with armature and of opposite polarity ahead of approaching pole
(ட in parallel with armature and of same polarity ahead of approaching pole
(D) in parallel with armature and of opposite polarity ahead of approaching pole
