The potential difference between a cloud and the Earth is `10^(7) V`. Calculate the amount of energy disspated when the charge of `100 C` is transferred from the cloud to the ground fue to lighting bolt.

The potential difference between a cloud and the Earth is 10^(7) V . Calculate the amount of energy dissipated when the charge of 100 C is transferred from the cloud to the ground due to lighting bolt.

Calculate the amount of energy dissipated when a charge of 200C is transferred from cloud to the ground during lighting, if potential of the cloud is 10^6V with respect to earth.

Calculate the amount of heat generated when 7200 coulombs of charge is transferred in one hour through a potential difference of 50 V.

The potential difference between two conductors is 110 V. How much work is moving 10C charge from one conductor to the other?

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 cpacitor . If the electric field between the cloud and ground exeeds the dielectric breakdown of the air (3xx10^(6)Vm^(-1)) lightning will occur. (a) If the bottom part of the cloud is 1000 m above the ground determine the electric potential difference that exists between the cloud and ground. (b) In a typical lightning phenomenon around 25 C of electrons are transferred from cloud to ground . How much electrostatic potential energy is transferred to the ground?
