Frequent question: What is electric fuse where it is connected in a circuit class 10?

[ – ] A fuse is connected in series at the begining of the circuit. The purpose of a fuse is to prevent over current from damaging the load or other parts of the circuit.

What is fuse How is it connected in a circuit for Class 10?

Answer: Fuses are always connected in series with the components to be protected from overcurrent, so that when the fuse blows (opens) it will open the entire circuit and stop current through the components.

What is electric fuse Class 10?

An electric fuse is an electric device which interrupts the flow of current in an electric circuit. … A fuse is usually a short piece of wire. The fuse is made up of a material which has high resistivity and low melting point, so that it melts down due to overheating of the wire during high current flow.

Where is a fuse connected in a circuit and why?

The fuse wire is always connected in the live wire of the electric circuit because if the fuse is somehow put in the neutral wire in the circuit, then due to excessive flow of electric current when the fuse burns, current will stop flowing in the circuit, but the appliance will still remain connected to the high …

What is fuse How is it connected in a circuit give its function?

Answer: The fuse in a circuit prevents over heating of the wires and appliances due to excess transfer of electric current and melts when more current passes through it. It is connected in series in domestic circuits.

Where is electric fuse in circuit?

The fuse is placed in the live wire just after the ‘electricity meter’ of the consumer. Fuse wires are generally made of an alloy of tin and lead and have a relatively low melting point.

What is electric fuse Class 7?

Fuse is a safety device that is a safeguard to all of our electrical appliances. They are made up of special material which melt quickly and break when large electric currents passed through it.

What is electric fuse?

In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current.

What is fuse in electric circuit?

The fuse breaks the circuit if a fault in an appliance causes too much current to flow. The fuse contains a piece of wire that melts easily. … If the current going through the fuse is too great, the wire heats up until it melts and breaks the circuit.

What is fuse short answer?

A fuse is a safety device in an electric plug or circuit. It contains a piece of wire which melts when there is a fault so that the flow of electricity stops. … When things fuse or are fused, they join together physically or chemically, usually to become one thing.

How a fuse is connected with mains in the circuit?

Additional information: The fuse is connected in series with the live wire before it enters the household circuit. This is done so because it is only the live wire which has a high potential of 200 volts unlike the neutral wire which carries zero potential. The fuse has a high rating of about 50 amperes.

Why is a fuse always connected to the livewire of the circuit?

The fuse wire is always connected in the live wire of the circuit because if the fuse is put in the neutral wire, then due to excessive flow of current when the fuse burns, current stops flowing in the circuit, but the appliance remains connected to the high potential point of the supply through the live wire.
