摘要:In this paper, we calculated thermal power, dissipated heat energy and radiated energy due to the current flowing in the body of lightning channel. The peak value of thermal power and total dissipated heat/thermal energy come out to be of the order of 1010 W and 106 J respectively. The calculated radiated energy comes out to be around 3.23 kJ. It is found that the energy lost in the form of radiation is much low as compared to the dissipated heat energy in the lightning channel.
