Precautions to avoid overloading of domestic electric circuit: (a) Avoid using too many appliances in a single line, i.e. from a single output. (b) Appliances should always be checked for potential faults and should be repaired in time. (c) Fuse or MCB of proper rating should be used.

The current drawn by the electric oven can be calculated using following formula: P=VI Or , I=P/V We have; P = 2kW = 2000 W and V = 220 V So, I=2000w/220V=9.09A Here, the oven is drawing 9.09 ampere of current from a 5 ampere source. This means there would be an overload on the circuit. This can resRead more
The current drawn by the electric oven can be calculated using following formula:
P=VI Or , I=P/V
We have; P = 2kW = 2000 W and V = 220 V
So, I=2000w/220V=9.09A
Here, the oven is drawing 9.09 ampere of current from a 5 ampere source.
This means there would be an overload on the circuit. This can result in accidental fire in the circuit.
