conversion of galvonometer into ammeter and voltmeter

This video gives complete explanation about how to convert galvonometer into ammeter and voltmeter

principle of shunt resistance

Shunt resistance should be connected in the circuit to save the galvonometer from very large currents and it is connected to moving coil galvonometer in parallel manner.

moving coil galvonometer

Moving coil galvonometer depends upon the principle that  a current carrying coil rotated itself when placed in a magnetic field. In this galvonometer, the deflection torque and restoring torque are equal

Force and Torque on a current loop in a magnetic field

This video tells about the effect of magnetic field when a current loop placed in a strong magnetic field and also explains about torque which acts as a deflecting torque on the current loop.

Fleming's Left hand Rule

Force between two parallel conductors carrying current

• Ampere showed that two parallel conductors carrying currents in the same direction have attractive force between them and carrying currents in opposite direction have repulsive force.
