Question

in some situations even through the liquid is conducting the bulb may not glow when connected to an electric tester. what can be the reason?

Answer 1

An electric bulb glows due to the heating effect of electric current. This means the filament of bulb gets heated to a high temperature and it start growing. However if the current through a circuit is too weak the filament does not get heated sufficiently and it does not glow. The current in the circuit maybe week due to many reasons. For example a material may be slightly conduct it may not conduct electricity as easily as a metal. As a result the circuit to the testa maybe complete and get the current through it may be too weak to make the bulb glow. Also the voltage of battery used in the electric tester may be quite slow so that even a material is good conductor but the current produced is very weak in the circuit. This current may not be sufficient to glow the bulb.

hope it helps you ☺️☺️☺️

$\huge \sf{Question :-}$

in some situations even through the liquid is conducting the bulb may not glow when connected to an electric tester. what can be the reason?

$\huge \sf {Answer :-}$

$\huge\green\rightarrow$ This happens when current through the circuit is too weak to make the bulb glow.

$\huge\green\rightarrow$ Liquid in the beaker may be non-conducting. In such a case, the electric current would not be able to pass through the liquid. Hence, the circuit will not be complete.

$\huge\green\rightarrow$A break in the filament of an electric bulb means a break in the path of the current between the terminals of the electric cell. Therefore, a fused bulb does not light up as no current passes through its filament.
