Question

explain short circuit and overloading 2. explain the force acting of a conductor when placed in a magnetic field through activity​

Answer 1

Answer:

Following are the difference between short circuit and overload: (a) Short circuit occurs when there is a fault between the line to earth while overload occurs when an equipment draws excess current from the supply.

A current carrying conductor placed in a magnetic field experiences a force. If the direction of the field and that of current are mutually perpendicular to each other, then the force acting on the conductor will be perpendicular to both and that can be determined using the Fleming's left-hand rule.(2)

Answer 2

Following are the difference between short circuit and overload:

(a) Short circuit occurs when there is a fault between the line to earth while overload occurs when an equipment draws excess current from the supply.

(b) Short circuit usually takes place when neutral and live wire touch each other while overload occurs when the number of devices joint in a single socket are more.

(c) During short circuit, the current is high whereas in overload, the current is comparitively low
