PHYSICS - Electricity - Lightning

The video explains the nature of lightning and thunderstorms, starting with Benjamin Franklin's experiment. It details how thunderstorms form due to charged particles in clouds, leading to lightning bolts. The video describes the characteristics of lightning, including its energy and effects, and discusses the challenges of harnessing lightning energy. Finally, it covers how cars, houses, and airplanes are protected from lightning strikes.

Who is credited with proving that lightning is an electrical phenomenon?

• Nikola Tesla

• Benjamin Franklin

• Thomas Edison

• Isaac Newton

What causes the rumbling sound of thunder?

• The movement of water molecules

• The rapid expansion and vibration of heated air

• The separation of electrical charges

• The collision of clouds

How much power does a single lightning bolt carry?
