👉 Is lightning static electricity or current electricity?

Both. A lightning bolt has many thousands of amps at millions of volts. The planet spins, but also has stationary waves through which it spins. It also has friction. Both of these cause the potential in the air to rise, as well as the earth. And yes..the earth has electricity in it. We don't create electricity from nature. We simply borrow it, make it do our bidding, and return it to ground...or "earth"

👉 Who discovered alternating current electricity?

Who Devised the Current Alternating Current Distribution System? Nikola Tesla was the first person who proposed to carry out electricity distribution with the alternating current. At that moment, he was working for Thomas Alva Edison's company. In 1887, Nikola Tesla managed to build the first prototype of an induction motor.

👉 What is current of electricity?

Current is the flow of electrons from one atom to the next. Current is measured in amps.
