Using the 'conduction tester' on an object it was found that the bulb begins to glow. Is that object a conductor or an insulator ? Explain.

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 very brightly for liquid A while it glows dimily for liquid B. You would conclude that.

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.
