Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
- 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
