What is an electric fuse Class 10?
An electric fuse is an electric device which interrupts the flow of current in an electric circuit. … A fuse is usually a short piece of wire. The fuse is made up of a material which has high resistivity and low melting point, so that it melts down due to overheating of the wire during high current flow.
What is electric fuse long answer?
Electric fuse is a safety device used to limit the current in an electric circuit which melts and breaks the circuit whenever there is an excess flow of current through the circuit.
What is fuse short 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 Ohm’s law class 10?
Ohm’s Law states that the current flowing through a conductor is directly proportional to the potential difference applied across its ends, provided the temperature and other physical conditions remain unchanged. Current is directly proportional to voltage difference through a resistor.
Why do we use electric fuses?
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.
