QUESTION 3 A lightning bolt might carry a current of 100 A and last for about...
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
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...
Chapter 20, Problem 002 An especially violent lightning bolt has an average current of 2.86 x 103 A lasting 0.139 s. How much charge is delivered to the ground by the lightning bolt? Number L the tolerance is +/-2% Click if you would like to Show Work for this question: Open Show. Work Units
You set up an iron lightning rod. Its is 5.0 meters tall, with the top sharpened to a point and the bottom in good contact with the ground. You’ve determined that lightning bolts typically carry about 30,000 amps of current and last around 60 microseconds. a. How much charge is delivered by a typical lightning bolt? b. If you want the potential difference between the top and bottom of the lightning rod to be less than 120 V, what is...
After several damaging lightning strikes during midwestern summer thunderstorms, you've decided to protect your house by setting up an iron lightning rod. The lightning rod is 6.0 meters tall, with the top sharpened to a point and the bottom in good contact with the ground. After some googling, you've determined that lightning bolts typically carry about 30,000 amps of current and last around 60 microseconds. a. Assuming that you can trust the internet, how much charge is delivered by a...
You've decided to protect your house by placing a 6.8-m-tall iron lightning rod next to the house. The top is sharpened to a point and the bottom is in good contact with the ground. From your research, you've learned that lightning bolts can carry up to 54 kA of current and last up to 50 ?s. Part A How much charge is delivered by a lightning bolt with these parameters? Express your answer to two significant figures and include the...
QUESTION 6 The allowed safe current for a No. 3 copper wire, 0.2294 inch in diameter, is 100 A. How many coulombs of charge pass a cross-section of the wire in 0.5 minutes? Assume the electron concentration in copper wire is about 2 x 102④ electrons/in3, the average electron velocity is about 2.5 inches/s, and the charge per electron is 1.6x 1019 C. (Enter your answer as a number with the coulombs units.)
PLEASE HELP!!! 8. Two long, parallel wires each carry a current I in the same direction as shown in the figure. The magnetic field at the point P, midway between the two wires is ________. zero directed into the page directed out of the page parallel to the wires in the same direction as the current. parallel to the wires, in the opposite direction as the current. 9. A long, straight wire carries a current of 20A to the right....
QUESTION 3 In the circuit shown below, the elements are R = 20 Ω , L-80 mH, and C = 100 μF. The voltage source is vs120 u(t). Determine the magnitude of the capacitor voltage vc (in volts) at the time t- 3 ms (three milliseconds). (Enter your answer as a number without the units.) C TV
A long straight wire has a hollow spherical conductor of radius R hanging from its end. The wire carries a downward current I. You are curious about the magnetic field, if any, that might exist just outside the "equator" of the sphere, i.e. the circle created by the intersection of the surface of the ball with a horizontal plane through its center, shown by the solid line a) What is the amount of charge on the sphere as a function...
