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
(1) liquid A is a better conductor than liquid B.
(2) liquid B is a better conductor than liquid A.
(3) both liquids are equally conducting.
(4) conducting properties of liquid cannot be compared in this manner.
Liquid A is a better conductor than liquid B.
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, the conductivity of liquid A is more than the conductivity of liquid B.
