PHYSICS - Electricity - Lightning

The video explains the nature of lightning, starting with Benjamin Franklin's experiment that proved lightning is an electrical discharge. It describes how thunderstorms form through charge separation in clouds, leading to lightning bolts. The video details the immense energy carried by lightning and the challenges of harnessing it. It also covers safety measures for protecting structures from lightning strikes.

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

• Isaac Newton

• Nikola Tesla

• Thomas Edison

• Benjamin Franklin

What causes the rumbling sound of thunder?

• The collision of clouds

• The rapid expansion and vibration of heated air

• The friction between charged particles

• The movement of water molecules

How much power does a single lightning bolt carry?

• 1 million watts

• 10 billion watts

• 100 million watts

• 5 billion watts

Why is it difficult to harness electricity from lightning?

• Lightning is too rare

• The equipment needed is too expensive

• Lightning strikes are unpredictable

• Lightning carries too little energy

How do airplanes protect passengers from lightning strikes?

• By avoiding thunderstorms

• By flying at lower altitudes

• By having a metal shell that conducts the charge away

• By using rubber tires
