Practicing Success
Moving coil galvanometer operates on a Permanent Magnet Moving Coil(PMMC) mechanism and was designed by the scientist D'arsnoval. It is of two types:
Its working is based on the fact that when a current carrying coil is placed in a magnetic field, it experiences a torque that rotates the coil about its axis of suspension in such a way that the magnetic flux passing through the coil is maximum. |
A moving coil galvanometer is used to measure which of the following? |
emf potential difference resistance it is a deflection instrument that gives a deflection when a current flows through its coil |
it is a deflection instrument that gives a deflection when a current flows through its coil |
