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.
What is an electric fuse class7?
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 electric fuse Class 8?
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 electric fuse class 10th?
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 explain briefly how does it work?
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 and types of fuse?
The main category of Fuses are based on the type of circuit they are used in i.e. AC Fuses and DC Fuses. Again, AC Fuses are divided in to High Voltage (HV) Fuses and Low Voltage (LV) Fuses. High Voltage (HV) AC Fuses are used for voltages above 1000V and Low Voltage (LV) AC Fuses are used for voltages less than 1000V.
What is a fuse in physics?
Definition: A strip or wire of metal inserted in an electric circuit, which melts (or ‘blows’) and so interrupts the circuit when the current increases beyond a certain safe strength.
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 short circuiting class 10th?
Short circuiting: It occurs sometimes that the live and neutral wires come in contact with each other, and this result is called short circuiting. In such instances, the resistance of a circuit decreases to an extremely small value. The decreasing of resistance results into the increase in the current.
What is electrical short?
An electrical short, or short circuit, is a low-resistance connection between two conductors (objects that allow electricity to flow through them) that are supplying electricity to a circuit. A short occurs when a current follows an unintended path, bypassing the route it’s supposed to take.
What is fuse Byjus?
In electrical and electronics, a fuse is defined as an electrical safety device that provides over-current protection to the functional electrical circuit. … It prevents short circuits. It acts as a barrier between the human body and electric current. It prevents overload and blackouts.
