Explanation
During a thunderstorm, a car acts as a protective enclosure because the metal body of the vehicle conducts electricity around the passengers and directs it safely to the ground. Therefore, the safest action is to remain inside the car.
What is Lightning?
Lightning is a sudden electrostatic discharge that occurs during a thunderstorm due to the buildup of electrical charges in clouds.
Why a Car is Safer During Lightning
• The metal body of the car acts like a Faraday cage
• Electric current flows around the outer metal surface
• Passengers inside remain protected if they avoid touching metal parts
Safety Measures During Thunderstorms
• Stay inside a closed vehicle or building
• Avoid standing under trees
• Avoid open fields and tall objects
• Do not touch metal poles or electric wires
