Question
What are the various reasons for excessive current in electric circuits? What can we do to prevent them? [3 MARKS]
Answer:
:
Reason: 2 Marks
Preventive measure: 1 Mark
The various reasons due to which there may be excessive current in electric circuits are:
1) Direct touching of wires. This may happen if the insulation on the wires has come out due to wear and tear. This may cause a short circuit.A short circuit can result in a very highcurrentflowing through the circuit.
2) Another reason for excessive current can be the connection of many devices to a single socket. This may cause overload in the circuit.
We can prevent excessive current in electric circuits by using a fuse, or MCBs.
