A lightning bolt has a current of 40,000 A and lasts for 50 x 10-6 seconds (50 us). How much charge (in Coulombs) has flowed in this bolt? E only, to two significant figures.
A cloud can discharge as much as 20 coulombs in a lightning bolt. If the bolt lasts only 0.1 msec, how many amps is that?
In a lightning bolt, a large amount of charge flows during a time of 2.1 10-3 s. Assume that the bolt can be treated as a long, straight line of current. At a perpendicular distance of 30 m from the bolt, a magnetic field of 7.8 10-5 T is measured. How much charge has flowed during the lightning bolt? Ignore the earth's magnetic field.
14. (10 pts) Lightning (a flow of electrons between the ground and a thundercloud) lasts about 120us. The rate of charge flow in a typical lightning bolt is about 25,000 coulombs per second. A) How much total charge flows between the ground and the cloud during a typical lightning bolt? B) How many electrons flow during this time? 15. (10 pts) 4 charges are placed at the corners of a square of side 1 m. What is the electric field...
Lightning occurs when there is a flow of electric charge (principally electrons) between the ground and a thundercloud. The maximum rate of charge flow in a lightning bolt is about 20,000 C/s this lasts for 100 μs or less. 1.How much charge flows between the ground and the cloud in this time? (Q= ? C) 2.How many electrons flow during this time? (n_e = ? )
