An electrical fuse is a safety device that operates to provide protection against the overflow of current in an electrical circuit. An important component of an electrical fuse is a metal wire or strip that melts when excess current flows through it.
What is an electric fuse Byjus?
Answer: 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 electric fuse short 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 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 Class 7?
A fuse is a safety device which limits current in circuit as a result it prevents damages to electrical circuits and possible fires. Fuses used in electrical appliances.
What is an electric fuse what is its important?
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 are electric fuses Why are they important?
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 electric fuse in Brainly?
Explanation: An electric fuse is a safety device used to limit the current in an electric circuit. The use of a fuse is to safeguard the electric circuit and the electric appliances connected in the electric circuit from being damaged.
What are the 3 types of fuses?
Different Types of Fuses – Constriction, Working & Characteristics
- DC Fuses.
- AC Fuses.
- Cartridge Fuses.
- D – Type Cartridge Fuse.
- HRC (High Rupturing Capacity) Fuse or Link Type Cartridge Fuse.
- High Voltage Fuses.
- Automotive, Blade Type & Bolted Type Fuses.
- SMD Fuses (Surface Mount Fuse), Chip , Radial, and Lead Fuses.
What is MCB full form?
MCB stands for Miniature Circuit Breaker. It automatically switches OFF electrical circuit during any abnormal condition in the electrical network such as overload & short circuitconditions.
What is electric fuse made up of?
Answer: Tin and lead alloy
An electrical fuse is a safety device in the circuit that protects electrical systems by breaking the connection when a short circuit is occurring. The fuse wire is made up of Sn (tin) and Pb (lead) alloy because of its high resistance and low melting.
What is the function of fuse for Class 7?
The basic function of a fuse is to prevent fire.It breaks the electric circuit if there occurs a fault in an electrical appliance that causes too much current flow. The fuse protects the wiring and the appliance if anything goes wrong.
