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

The distinctive brightness levels observed in the bulb of the tester when assessing the conduction of electricity through liquids A and B point towards varying degrees of conductivity in these substances.

1. Liquid A – Effective Conductor: The bright and intense glow observed while testing liquid A indicates its proficiency as a good conductor of electricity. This brightness suggests the presence of ions or conductive elements within the liquid, allowing for the efficient flow of electric current.

2. Liquid B – Limited Conductivity or Insulation: The significantly dim glow of the bulb during the examination of liquid B implies its limited ability to conduct electricity. This scenario suggests that liquid B either possesses poor conductivity or acts as an insulator, hindering the flow of electric current due to the absence or scarcity of ions or conductive elements.

Hence, based on the observed brightness levels:

– Liquid A demonstrates traits of an effective conductor, facilitating a robust flow of electricity.
– Liquid B exhibits characteristics of either limited conductivity or acting as an insulator, impeding the flow of electricity and resulting in a minimal current passage.
