the question is from TPR ICC and for some reason it is just not clicking:
Before lightening strikes air between the a cloud and a ground acts as an insulator, what describes the effect of the air?
The answer is basically that air reduces the potential difference between the cloud and the ground...
I know Q=VC so as C increases (bc of the air) V decreases? (im assuming potential difference is Voltage.. )
Also can someone explain why when an electron travels from a thundercloud to the ground it causes a decrease in potential energy as it moves toward a region of higher electric potential... i just can't seem to comprehend something decreasing PE by moving to a higher electric potential... seems so counter intuitive
