Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If lightning strikes a car, the people inside it are protected by the rubber tires of the car acting as insulators.
A
TRUE
B
FALSE
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Car tires do not protect you from lightning strikes. Although the rubber in a tire acts as an insulator at low voltages, the voltage in a lighting bolt is far too high to be stopped by tires or air.

Detailed explanation-2: -Rubber does not protect you from lightning. Rubber is indeed an electrical insulator, but your shoes or bike tires, for instance, are way too thin to protect you from a lightning strike.

Detailed explanation-3: -True or false: Your car’s rubber tires will protect you if lightning strikes your car. False! John Jensenius of the National Lightning Safety Council says it’s the type of car – not the tires – that protect you from lightning. You’re the safest in a hard-topped vehicle.

Detailed explanation-4: -Generally, strikes cause damage to the electrical system, the antenna, the tires and the rear windshield. Intense strikes can also ignite a fire within your vehicle, rendering it inoperable and endangering your life.

Detailed explanation-5: -Materials that don’t conduct electricity (with very few free electrons or even no free electrons) are called insulators. Rubber is an insulator as electrons are tightly held so that no electrons are free to move. Q. Generally, non-metals are not good conductors of electricity.
