Question:

Match List I with List II

List I		List II
A.	Ammeter is made	I.	By connecting a high resistance in series with moving coil Galvanometer
B.	Voltmeter is made	II.	Increases the strength of magnetic field
C.	Soft ion core in moving coil galvanometer	III.	Increases torque produced in coil
D.	Radial field in moving coil galvanometer	IV.	By connecting a low resistance in parallel with moving coil Galvanometer

Choose the correct answer from the options given below:

Options:

A-IV, B-III, C-I, D-II

A-II, B-III, C-IV, D-I

A-I, B-II, C-III, D-IV

A-IV, B-I, C-II, D-III

Correct Answer:

A-IV, B-I, C-II, D-III

Explanation:

Ammeter is made by connecting a shunt resistance of low value with the galvanometer coil.
Voltmeter is made by connecting a high resistance in series with galvanometer coil.
Soft iron core in MCG increases susceptibility and thus strength of magnetic field
Radial field in MCG increases torque produced in the coil. As torque depends on radial field
