Fuse is a safety device which is connected before the appliance in
Answers
Answer: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.
A 13A fuse contains a low melting point wire
Fuses in plugs are made in standard ratings. The most common are 3 A, 5 A and 13 A. The fuse should be rated at a slightly higher current than the device needs:
if the device works at 3 A, use a 5 A fuse
if the device works at 10 A, use a 13 A fuse
Circuit breakers
Circuit breakers act as resettable fuses.
