Moving Coil Galvanometer |
Moving coil galvanometer operates on Permanent Magne Moving Coil (PMMC) mechanism and was designed by the scientist D'arsonval. |
Moving coil galvanometers are two types |
(i) Suspended coil |
(ii) Pivoted coil type or tangent galvanometer. |
Its working is based on the fact that when a current carrying coil is placed ina magnetic field, it experiences a torque. This torque tends to rotate the coil about its axis of suspension in such a way that the magnetic field passing through the coil is maximum. |
A) is used to measure emf
B) is used to measure potential difference
C) is used to measure resistance
D) is a deflection instrument which gives a deflection when a current flows through its coil
Correct Answer: D
Solution :
A moving coil galvanometer is a sensitive instrument which is used to measure a deflection when a current flows through its coil.You need to login to perform this action.
