Water obtained from which of the following sources is a good conductor of electricity?

physics chemical effects of electric current does liquid conduct electricity? liquids conduct electricity do liquids conduct electricity?

  1. Tap

  2. Ponds

  3. Wells

  4. All of the above

Show answer
Correct Option: D
Explanation:

The water that we get from sources such as taps, hand pumps, wells and ponds is not pure. It may contain several salts dissolved in it. Small amounts of mineral salts are naturally present in it. This water is thus a good conductor of electricity.
