Show Liflhtning Strokes With retrard to the voltaic of linht-ning linht-ning strokes there are only estimates. These range from a few hundred thousand thou-sand to several billion volts, depending upon the Ideas of Uie persons making the estimates. No measurements hnvo 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 23,000 am. peres. As for harnessing lightning and turning it into energy useful to man, no practicable scheme has yet been presented. |
