Question

Air is a poor conductor of electricity but during lighting electricity travels through the air why is it so.

Answer 1

Air is a poor conductor of electricity, that's true. But lightning not actually 'travel' through air, it's 'discharging'through air. When the potential difference (or voltage) between 2 points are very high, the insulator in between has very high stress. ... Anything conducts at high enough voltage.
