(1) A large lightning bolt had a 20,500 A current and moved 32.5 C of charge. What was its duration (in ms)? (2) A power transmission line is hung from metal towers with glass insulators having a resistance of 2.55 ✕ 109 Ω. What current (in mA) flows through the insulator if the voltage is 280 kV? (Some high-voltage lines are DC.)
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.
The current in a lightning bolt is 2.0 ✕ 105 A. How many coulombs of charge pass through a cross-sectional area of the lightning bolt in 0.57 s? ______C
Assume that a lightning bolt can be represented by a long straight line of current. If 15.0 C of charge passes by in a time of 1.5·10-3s, what is the magnitude of the magnetic field at a distance of 22.0 m from the bolt?
During a thunderstorm, a lightning "bolt" carries current between a cloud and the ground below. If a particular bolt carries a total charge of 15 C in 1.5 ms, what is the magnitude of the current? A How many electrons are involved in this process? electrons
In a lightning bolt, 12 C of charge flows in a time of 1.5 times 10^-3 s. Assuming that the lightning bolt can be represented as a long, straight line of current, what is the magnitude of the magnetic field at a distance of 26 m from the bolt? 61.53e-12 T
