Question

A tester is used to check the conduction of electricity through two liquids, labeled A and B. It is found that the bulb of the tester glows brightly for liquid A while it glows very dimly for liquid B. You would conclude that

• A. liquid A is a better conductor than liquid B.
• B. liquid B is a better conductor than liquid A.
• C. both liquids are equally conducting.
• D. conducting properties of liquid cannot be compared in this manner.

Answer 1

The correct option is A

liquid A is a better conductor than liquid B.

1. The conductivity of a solution determines the amount of current flowing through it.
2. As the conductivity increases, the amount of current passing through the solution increases.
3. As the conductivity decreases, the amount of current passing through the solution decreases.
4. As a result, liquid A has a higher conductivity than liquid B.

Hence, Option(A) is correct.
