Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If lightning strikes a car, the people inside it will not be electrocuted because the tires of the car act like 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: -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-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: -When the lightning strikes the surface of the car, the charge flows over the outer surface of the car and there is no charge inside the car body. Accordingly, the electric field inside the car is zero.

Detailed explanation-5: -Static electricity is the buildup of electric charges on an object. This buildup of electrons after transferring electrons occurs as oppositely charged items are brought close to each other. Lightning is an example of static discharge of built up static electricity.
