What is an electric fuse What are its two uses?
The electric fuse is a piece of wire having a very low melting point and high resistance. An electric fuse is used as a safety device for the protection of electric circuits and appliances due to short-circuiting or overloading of the electric circuits. answer.
What is electric fuse What is its role in electric circuit should it be placed on neutral wire or on live wire justify your answer?
Fuse should be placed on live wire because the live wire has the higher voltage. If the live wire is damaged inside the appliance and a large current is created, then the fuse needs to be in this part of the circuit so that it can blow.
What is an electrical fuse state two characteristic of an electrical 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 a fuse write its uses?
An electric fuse is an electrical safety device that is used for the purpose of preventing a short circuit. It is installed in electrical circuits or devices to prevent the device from damage due to excessive flow of current.
What is an 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 an electric fuse why it is used in electric circuit?
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 the role of electric circuit?
Electric circuit, path for transmitting electric current. An electric circuit includes a device that gives energy to the charged particles constituting the current, such as a battery or a generator; devices that use current, such as lamps, electric motors, or computers; and the connecting wires or transmission lines.
What is electric fuse What are its characteristics?
(a) The electric fuse is a device used to limit the current in an electric circuit. It has following characteristics: (i) Fuse has high resistance and low melting point. (ii) Fuse is made up of the aolly of lead and tin. (iii) Fuse is always connected to the live wire of the circuit.
What characteristics should a fuse have?
High melting point, low specific resistance.
