What is the function of fuse wire?
Answers
The function of a fuse wire is an electrical safety device that operates to provide overcurrent protection of an electrical circuit.
Answer:
A Fuse acts as an overload protection device for an electric circuit and electric appliances.
Explanation:
A Fuse is a device in which a very thin wire is attached, that thin wire has two specific characteristics.
Low Melting Points: Fuse wires are made up of such material which has a low melting point but high resistance to break on overload and protect circuits and appliances.
High Resistance: The Cross-section area of the wire is very thin due to which the flow of electrons gets hindered and high resistance is created.
Working: As explained that fuse wire has very high resistance and low melting points so on passing excess current or in the situation of overload fuse wire breaks because on high resistance wire gets heated and starts melting because of low melting point. On the breaking of fuse wire, the electric circuit becomes incomplete and current stops flowing, and electric appliances become safe from further damage.
