Question
A spark of artificial 10.0-MV lightning had an energy output of $0.125 \mathrm{MW} \cdot \mathrm{s}$. How many coulombs of charge flowed?
Step 1
We know that 1 MW is equal to 1,000,000 W, so 0.125 MW is equal to 125,000 W. Since the energy output is given in MWs, we can convert it to joules by multiplying by the time in seconds: Energy = Power × Time Energy = 125,000 W × 1 s Energy = 125,000 J Now, we Show more…

Estimated at 10 Coulombs. The amount of charge carried by a lightning bolt. What quantity of excess electrons (N) is carried by the lightning bolt? (e = -1.6 * 10^-19C) 6.25 x 10^19 electrons 16 x 10^-19 electrons 6.25 x 10^-19 electrons 16 x 10^19 electrons
During a thunderstorm, a lightning "bolt" carries current between a cloud and the ground below. If a particular bolt carries a total charge of $20 \mathrm{C}$ in $1.0 \mathrm{ms}$, what is the magnitude of the current? How many electrons are involved in this process?
