Question
A tester is used to check the conduction of electricity through two liquids, labelled 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 ______.
Options
liquid A is a better conductor than liquid B.
liquid B is a better conductor than liquid A.
both liquids are equally conducting.
conducting properties of liquid cannot be compared in this manner.

Solution
A tester is used to check the conduction of electricity through two liquids, labelled 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 Liquid A is a better conductor than liquid B.
Explanation:
The amount of current flowing through a conducting solution depends on the conductivity of the solution. With more conductivity, more current passes through the solution and vice versa. Hence, liquid A's conductivity is greater than liquid B's.
