Multiple choice

Air is a poor conductor of electricity but still it is conducting under some conditions. Which of the following is such a condition?

  1. During rainfall, air becomes wet and like all wet things becomes a good conuctor of electricity.

  2. During a thunderstorm, lightning occurs which is an electric current passing through air.

  3. During a dust storm, the particles of dust collide with each other leading to electrostatic charging of air making it a good conductor.

  4. Air passing through high tension wires gets charged and can conduct electricity.
