Mini-Quiz: Lightning Protection System

by Ron Kurtus (revised 14 April 2011)

Take this Mini-Quiz to check your understanding of the lesson material.



1. Why should farm houses and barns have lightning rods installed?

Farm houses and barns are often the highest objects in the area

To attract lightning to use for added electrical power

They are cheaper than using static wicks

2. Why is a lightning arrester used in many large buildings?

They are much better than old-fashioned lightning rods

To avoid damage to electronic equipment if a power line is struck by lightning

So the current will pass through the metal skin of the building

3. Why aren't more aircraft damaged by lightning strikes?

Many aircraft are destroyed each year, but the news is repressed

Many can outrun the lightning bolts

They try to avoid thunderstorms and have a good protection system

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.
