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
(i) liquid A is a better conductor than liquid B.
(ii) liquid B is a better conductor than liquid A.
(iii) both liquids are equally conducting.
(iv) conducting properties of liquid cannot be compared in this manner.
Dear Student,
Answer:
(i) liquid A is a better conductor than liquid B
Explanation:
Liquid A is a better conductor than liquid B.
The bulb's brightness relies on the current that flows through the bulb, which in turn depends on the liquid's overall conductivity. Since the bulb's brightness is greater in liquid A as compared to liquid, we can conclude that liquid A is a stronger conductor than liquid B.
