Question

Give the theory of moving coil galvanometer.

Answer 1

Answer:

Explanation:

Principle: When a current-carrying coil is suspended in a uniform magnetic field it is acted upon by a torque. Under the action of this torque, the coil rotates and the deflection in the coil in a moving coil galvanometer is directly proportional to the current flowing through the coil.

The torque on a current loop in a uniform magnetic field is used to measure electrical magnetic field is used to measure electrical currents. This current measuring device is called a moving coil galvanometer. The galvanometer consists of a coil of wire often rectangular, carrying the current to be measured.

Answer 2

Answer

Moving coil galvanometer:

It is a device used for measuring the current in a circuit.

It is a device used for measuring the current in a circuit. It works on the principle that a current carrying coil placed in a magnetic field experiences a torque.
