Question

3. During a thunder storm, the movement
of water molecules within the clouds
creates friction, partially causing the
bottom part of the clouds to become
negatively charged. This implies
that the bottom of the cloud and the
ground act as a parallel plate capacitor.
If the electric field between the cloud
and ground exceeds the dielectric
breakdown of the air (3 X 106 Vm" ),
lightning will occur.​
