Question

Identify the examples of the bad conductors of electricity from the following options.

• A. Sulphuric acid
• B. Air
• C. Rubber
• D. $H_{2}O$

Answer 1

Answer: (B), (C), (D)

$H_{2}O$

To be a good electric conductor, a material needs to have free electrons or ions.
Sulphuric acid has $H^{+}$ and $S{O}_4^{-}$ ions.
$H_{2}O$ is pure water which does not have any salts and is a bad conductor of electricity.
Air and rubber are also bad conductors as they have no free electrons or ions.
