Answer 1

Normally, air doesn't conduct electricity, and acts as an insulator, but just like everything else in nature, it has it's limit.

But if the voltage rises beyond that, the phenomena of 'insulator breakdown' occurs and air starts conducting. This is often accompanied with sparking.

You must also have noticed, that when walking around transmission lines, you hear a hissing sound. That is due to the breakdown of O2 into single O molecules, which then combine with molecular oxygen to for ozone.

Applications:-

1. Lightning.

2. Sparking

3. Hissing sound in transmission lines.

Answer 2

Answer:

Lighting

Explanation:

Because it has higher amount of electricity that air can not stop it
