Question

Answer Briefly
1. What is meant by an open circuit? Why does electric current not pass in this case?
2. Why does a nichrome wire get heated in an​

Answer 1

Answer:

1.A circuit must be complete for the switch to be "on" if there is any break or open spot, it is an "open circuit".

Open circuit are not complete. therefore, electricity doesn't flow.

2.Nichrome due to its high resistivity does not allow the electric energy easily to pass through it. This electrical energy is changed into heat energy. So nichrome wire gets heated in an electric circuit.
