Chemical Effects of Electric Current


The bulb does not glow in the setup shown in Fig.14.10. List the possible reasons. Explain your answer.


The possibility of the bulb not glowing may be because of the following reasons:

(i). The liquid may be non-conducting. In this case, the electric current will not pass through the liquid. Here, the circuit is incomplete.

(ii). Electric current may be weak in the circuit, maybe because the circuit is made up of a material which is not a good conductor of electricity or there is insufficient energy in the battery to generate electricity.
