The bulb does not glow in the setup shown in figure given alongside. List the possible reasons. Explain your answer.
Answer:
The bulb may not glow because of the following reasons:

  • Liquid in the beaker is non-conducting. In such case, the electric current would not be able to pass through the liquid. Hence, the circuit is not complete.
  • Electric current in the circuit is very weak. This can happen if the material used for making the circuit is not a good conductor of electricity or the battery does not have sufficient energy to generate electricity.
