Mock Test on Galvanometer for Students

M.C.G. is based on :

(A) the heating effect of the current

(B) the chemical effect of the current

(C) the magnetic effect of the current

(D) the thermoelectric effect

Show Answer

(Α) 15 Ω

(B) 20 Ω

(C) 80 Ω

(D) 40 Ω

Show Answer

When a current is passed in a moving coil galvanometer the coil gets deflected because

(A) The current deflects anything

(B) the Current in the coil produces a magnetic field

(C) the Current in the coil produces an electric field

(D) A couple acts on the coil

Show Answer

The current that must flow through the coil of the galvanometer so as to produce a deflection of one division on its scale is called :

(A) Micro-volt sensitivity

(B) Current sensitivity of a galvanometer

(C) Charge sensitivity of the galvanometer

(D) Both '1' and '2'

Show Answer

Show Answer

The pole pieces used in moving coil galvanometer should produce a magnetic field :

(A) Equal to earth's magnetic field

(B) Much stronger than earth's magnetic field

(C) Much weaker than earth's magnetic field

(D) Any arbitrary magnetic field

Show Answer

A soft iron core is placed at the center of the rectangular coil in M.C.G because

(A) It increases the magnetic field

(B) It decreases the magnetic field

(C) More current passes through the coil

(D) No effect of the iron core
