Explanation: – 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 in a fuse?
A fuse commonly consists of a current-conducting strip or wire of easily fusible metal that melts, and thus interrupts the circuit of which it is a part, whenever that circuit is made to carry a current larger than that for which it is intended.
What is the definition of fuse in science?
A fuse is a small, thin conductor designed to melt and separate into two pieces for the purpose of breaking a circuit in the event of excessive current. A circuit breaker is a specially designed switch that automatically opens to interrupt circuit current in the event of an overcurrent condition.
Do fuse stands for?
Foundation for Upgrading the Standard of Education.
What is fuse question 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 a fuse Class 7 Ncert?
A fuse is a safety device made up of a conducting material having low melting point. It works on the principle of heating effect of current.
What is fuse example?
When you overload the circuit in your house by turning on too many different appliances at once and your power to the appliances you are using shuts off, the electrical device that tripped and caused the power to stop to the overloaded circuit is an example of a fuse.
What is fuse and its function?
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 fuse and its types?
The fuse is the current interrupting devices which break or open the circuit by fusing the element and thus remove the faulty device from the main supply circuit. The fuses are mainly classified into two types, depends on the input supply voltages they are the AC fuses and the DC fuses.
What is a fuse or circuit breaker?
Fuses and circuit breakers are both designed to interrupt the flow of electricity. But they operate through different mechanisms. 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.
What is a fuse Class 6?
A fuse is a safety device made up of a conducting material having low melting point. It works on the principle of heating effect of current.
What is fuse define it class 9?
A fuse is a piece of wire of a material with a very low melting point, that is, it melts and breaks as soon as its temperature gets higher than its melting point. The material used for making fuse have low melting points , hence fuse wires are mainly made up of tin, lead or zinc.
What is an electric fuse Class 7 answer?
Class 7 answer 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.
