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 an electric fuse answer?
An electric fuse is an electric device which interrupts the flow of current in an electric circuit. It is installed in a circuit to stop the flow of excessive current. A fuse is usually a short piece of wire. … Normally an alloy of tin and lead is used as the fuse wire, as it has high resistivity and low melting point.
What is an electric fuse in physics?
An electrical fuse is a low melting point copper or other metal wire that breaks due to heat caused by overvoltage or high load to avoid short circuit or failure to the device.
What is an example of a fuse?
The definition of a fuse is an electrical safety device that can stop current from flowing if it becomes overloaded, or a device that is used to ignite an explosive device. … The little string sticking out of a bomb that you light in order to get the bomb to go off is an example of a fuse.
What is the use of an 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 an electric fuse what are its benefits?
Fuse is the cheapest protection device in electrical circuit against short circuits and overloading of circuits. … Fuse provides protection against excessive currents which can flow in circuit during short circuits.
What is the role of an electric switch?
An electric switch is a device that interrupts the electron flow in a circuit. … The function of an electric switch is to regulate the current between the load and source of power. The power source is the electrons that push through the circuits.
What is fuse in simple words?
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.
What is the difference between a fuse and a circuit breaker?
Fuses and circuit breakers are both designed to interrupt the flow of electricity. … The fuse works as a piece of metal that melts down when overheated. While a circuit breaker works by operating a switching mechanism when an overflow of electricity is detected.
Which type of accessories of fuse is comes under?
Fuses are a type of resistor with the main purpose of providing overcurrent protection in various different electrical applications. Electrical fuses and the compatible accessories such as holders, blocks, and panels designed to meet circuit protection requirements in electric and vehicle applications.
