Question

Any scientist ever measured Voltage & Current of a lightning & how much it is ?

Answer 1

An average bolt of negative lightning carries a current of 30-to-50 kiloamperes, transfers a charge of 5 coulombs, and dissipates 500 megajoules of energy (enough to light a 100 watt light bulb for 2 months). However, an average bolt of positive lightning (from the top of a thunderstorm) may carry a current of 300-to-500 kiloamperes, transfer a charge of up to 300 coulombs, have a potential difference up to 1 gigavolt (a billion volts), and may dissipate enough energy to light a 100 watt lightbulb for up to 95 years.

Answer 2

1.21 Jigowatts

Answer 3

minimum 250 walt
