Lightning occurs when there is a flow of electrons between the ground and thethunder cloud. the maximum rate of flow (current) is about 20,000 c/s (amps), andit lasts for about 100 microseconds. how much charge flows between the groundand the cloud in this time? how many electrons flow during this time?

In a set amount of time, a battery supplies 25j of energy to an electric circuit that includes two different loads. one of the loads produces 10 j of heat energy during this time interval. how much heat energy is produced by the second load in this time? explain your answer
