Listed below are two instances of when a short-circuit can occur:
1) When too many appliances are connected to a single socket or when high power rating appliances are connected to a light circuit, the resistance of the circuit becomes low as a result the current flowing through the circuit becomes very high. This condition results in a short-circuit.
2) When live wires whose insulation have worn off come in contact with each other, the current flowing in the circuit increases abruptly, which results in a short circuit.Answered by Shivani Kumari | 1 year ago
State the rule to determine the direction of an
(i) magnetic field produced around a straight conductor carrying current,
(ii) force experienced by a current-carrying straight conductor placed in a magnetic field which is perpendicular to it, and
(iii) current induced in a coil due to its rotation in a magnetic field.
