Small current in a circuit is detected by


Galvanometer is used to detect presence of small current in a circuit


Induced current found to be highest when coil moves


The induced current is found to be the highest when the direction of motion of the coil is at right angles to the magnetic field.


On & off switch is provided with


No current flows through the neutral wire , the technical purpose of switching on and off can be accomplished if switch is connected to the neutral wire but it is a greivious safety hazard since switching off would still current flow in the phase wire ( live wire)


Fuse wire used in lighting circuit is of


Fuse is a piece of wire of a material with a very low melting point. When a high current flows through the circuit due to overloading or short circuit, the wire gets heated and melts. As the result, the circuit is broken and current stops flowing.  Hence, the current rating of a fuse is 5 A. 


In the domestic electric circuits, the red coloured insulated copper wire is called

Solution: The live wire carries current to the appliance at a high voltage. The neutral wire completes the circuit and carries current away from the appliance. The third wire, called the earth wire (green/yellow) is a safety wire and connects the metal case of the appliance to the earth.
