Question

How high voltages are generated by lightning?

Answer 1

✔✔✔✔Ur answer✔✔✔✔



⭐⭐⭐Strong electric fields ✔✔✔(from high voltages applied to small or pointed conductors)✔✔✔✔✔✔ often produce ⭐violet-colored⭐ corona discharges in air as well as visible sparks.✔✔✔

✔✔✔✔✔✔✔✔✔✔✔✔✔

⭐⭐⭐⭐⭐Voltages below about ⭐500–700⭐ volts cannot produce easily visible sparks or glows in air at ___________$____________atmospheric pressure so by this rule these voltages are ✔✔✔low✔✔✔

Answer 2

we learn that lightning bolts carry from 5 kA to 200 kA and voltages vary from 40 kV to 120 kV. So if we take some averages, say, 100 kA and 100 kV, this bolt would carry this much power, P:

P = 100×103 A  x 100 x 103 V

= 10,000 x 106  VA or Watts

= 1 x 1010 Watts

Recall that 1010  Watts is 10,000,000,000  or 10 billion Watts.

Now assume this energy is released in 1 sec. So the power is:

1010 W-sec. On your electric bill, you’ll see you pay for Watt-hours or Wh. So let’s convert W-sec to Wh:

Pl = 1010 Ws x 1 hr/3600 s

Pl = 1/36 x 108 Wh

= 0.0277 x 108

= 2.7 x 106 Wh or Watt-hour per our average lightning bolt.
