Answer 2

Corrected question: Given below is a circuit diagram. The beaker is filled with distilled water and the two terminals are dipped in it. It is observed that the bulb does not glow in this arrangement. In what condition can the bulb glow.

Answer:

The bulb does not glow in this condition because distilled water is a bad conductor of electricity.

• When the terminals are put in the beaker filled with the distilled water, the flow of current in the circuit stops as distilled water does not conduct electricity.
• Distilled water does not conduct electricity as it is completely pure and free from any electrolytes.
• We can make the bulb glow by adding electrolytes to the water. NaCl or table salt can be used in this condition as it is easily available and soluble in water.

So, we can conclude that the bulb does not glow in distilled water due to the absence of electrolytes and this can be fixed by adding an electrolyte like NaCl to the water.
