Your question: What is electric fuse and its properties?

What are the properties of an electric fuse wire?

Characteristic properties of a fuse wire: (i) It is made up of an alloy of lead and tin. (ii) It has high resistivity and low melting point.

What is called electric fuse?

Electric fuse is a safety device used to limit the current in an electric circuit which melts and breaks the circuit whenever there is an excess flow of current through the circuit.

What is electric fuse also write two properties of electric fuse?

Its characteristics are: (i) It has a low melting point (m.p.) of about 200°C and is usually made from an alloy of 50% tin and 50% lead. (ii) It has a high resistance so that its temperature rises rapidly and soon exceeds its m.p. and thus breaks it, when current passing through it exceeds the permissible limits.

What is an electric fuse describe its characteristics?

(a) The electric fuse is a device used to limit the current in an electric circuit.

What are the properties of electric fuse Class 10?

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. The thickness of the fuse wire is determined based on the amount of current flow in the circuit.

What is electric fuse?

The fuse breaks the circuit if a fault in an appliance causes too much current to flow. This protects the wiring and the appliance if something goes wrong. 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?

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 wires gets heated and melts. As a result, the circuit is broken and current stops flowing.

What is electric fuse Class 10?

Electric fuse is a small piece of wire of a material having low melting point and high resistance. The device protects the circuit from overloading and short circuiting. A fuse wire is made of pure tin or of an alloy of copper and tin.

What is a fuse wire class 10?

Fuse wire is used to break the circuit when the load is high so that higher currents do not damage the appliances. … Fuse is an essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current.
