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

Answer
Liquid A is a better conductor than liquid B.
Reason — The brightness of the bulb is determined by the current through the circuit, which in turn depends on the conductivity of the solution. The greater the conductivity, the greater will be the quantity of current passing through the solution and as a result the bulb will glow brightly. Hence, liquid A is a better conductor than liquid B as the bulb glows more brightly in liquid A.
