what are short circuiting? state one factor /condition that can lead to it. Name a device in the household that acts as a safety measures for it. state the principal of its working.
Answers
Explanation:
When the current in the circuit abrupty or highly increases is called as short -circuiting.
The factor is by connecting too many appliances to a single socket leads to short circuiting.
A fuse acts as safety measure for it.
The principal is that the Joule heating takes place in the fuse and melts it to break the electric circuit.
Situation in which live and neutral wire come in direct contact, abruptly increasing the current in
the circuit is called short-circuiting.
Factor - Insulation of wire is damaged / fault in appliance.
Safety device - electric fuse.
Electric fuse is an application of Joule’s heating. If there is a current larger than the specified value the temperature of [use wire increases and it melts to break the electric circuit and stop the flow of unduly high electric current.
