Question

A student makes an arrangement to test the electrical conductivity of distilled water as shown . The student observes that the bulb does not glow what could be the reason the bulb doesn’t glow

Answer 1

Answer:

$\huge\mathbb\pink{ANSWER}$

Solution:

Following can be the reasons why bulb does not glow :

The liquid solution in the beaker might be distilled water.

The liquid solution used in the beaker might be a poor conductor of electricity.

The bulb might be fused.

The battery might already be exhausted, sufficient electric charge to light the bulb is not present.

There might be any loose connection in the circuit between the wires, bulb,battery or electrodes.

Answer 2

Answer:Distilled water do not consists of the necessary salts in it.

Explanation:

• When the students dip the tip into the beaker containing distilled water, the bulb won't glow.
• It is because the distilled water do not contain the salts in it.
• The salts which helps in conducting electricity is missing in distilled water.
