Show Lightning Strokes With regard to the voltage of lightning light-ning strokes there are only estimates. These range from a few hundred thousand thou-sand to several billion volts, depending upon the Ideas of the persons making the estimates. No measurements havo been made. The amperage of lightning light-ning strokes is more definitely known, a few attempts having been made to measure it. The best measurements of this kind show that the current Intensity In-tensity may be as great as 25,000 amperes. am-peres. As for harnessing lightning and turning it into energy useful to man, no practicable scheme has yet been presented. |
