    Car Rubber Tires

SUMMARY

The discussion clarifies that the common belief of being safe in a car during a lightning strike is primarily due to the car acting as a Faraday cage, rather than the rubber tires. The concept of Gausse's Law is referenced to explain the protective properties of the car's structure. The insulation provided by the car's interior contributes to safety, but the primary factor is the Faraday cage effect, which is effective regardless of the car's material composition.

PREREQUISITES
  • Understanding of Gausse's Law
  • Knowledge of Faraday cages
  • Basic principles of electrical insulation
  • Familiarity with the physics of lightning
NEXT STEPS
  • Research the principles of Faraday cages in detail
  • Explore the effects of lightning strikes on various materials
  • Learn about the physics of electrical insulation
  • Investigate safety measures in vehicles during thunderstorms
USEFUL FOR

Physics enthusiasts, electrical engineers, safety professionals, and anyone interested in understanding the science behind lightning protection in vehicles.

So I just learned Gausse's Law and it makes me think: People always say you're safe in a car if it get struck by lighting because of the rubber tires (odd, because tired are like 90%carbon) but isn't it also because a car is a Gaussian sphere? The interior is insulated, sort of, right? If this is true, is the protection from a car acting as a Gaussian Sphere greater or less than the little amount of rubber in the tires?

Hello Dow, welcome to PF :smile: !

Rubber tyres is a myth. Faraday cage (so a plastic car doesn't help...) is the protection. Insulation helps.

Think of people in an airplane struck by lightning. I never heard of any of them being shocked.
 
Thanks for the info!

My thoughts exactly! Hey, this physics stuff is kinda cool...
