Q1 (Easy): Choose the incorrect statement: (i) A switch is the source of electric current in a circuit. (ii) A switch helps to complete or break the circuit. (iii) A switch helps us to use electricity as per our requirement. (iv) When the switch is in 'OFF' position, there is an air gap between its terminals.

Answer:
We have studied that electric cell is the source of electrical energy in a circuit. This is why statement (i) is incorrect.

  • Switch only completes or breaks the circuit
  • Electric cell provides the electrical energy to circuit
  • Switch helps us control electricity as needed
  • Air gap exists when switch is OFF position
Switch vs Electric Cell Function Switch Electric Cell Purpose Controls circuit Provides energy Action Completes/breaks circuit Source of current Position ON or OFF Always active Energy No energy source Portable energy source
