The narrator in "The Lightning-Rod Man" is skeptical, practical, and cautious. He questions the sales pitch of the lightning-rod man and ultimately decides against purchasing his product due to its dubious effectiveness.
Lightning rods are typically made of metal and do not need to be particularly thick to conduct lightning. The most important factor is the material's conductivity, such as copper or aluminum, which allows the lightning to safely pass through the rod and into the ground. The diameter of a lightning rod is usually around ½ inch to 1 inch.
A lightning rod is a metal rod installed on the roof of a building to intercept lightning strikes and safely conduct the electrical charge to the ground, thus preventing it from causing a fire inside the house. The rod provides a path of least resistance for the lightning to follow, protecting the structure by dissipating the potentially harmful electrical energy.
Yes, a lightning rod mounted on a tall building can help protect the structure by providing a path for the lightning strike to safely reach the ground without causing damage. The rod will attract the lightning strike and conduct it harmlessly to the ground, reducing the risk of fire or structural damage. It is important for the lightning rod to be professionally installed and maintained to ensure its effectiveness.
Ben Franklin
If a glass ball on a lightning rod is struck by lightning, it may shatter due to the extreme heat generated by the lightning strike. Additionally, the lightning may travel through the rod to the ground, protecting the building from damage.
The main purpose of these glass balls is to provide evidence of a lightning strike by shattering or falling off. If after a storm a ball is discovered missing or broken, the property owner should then check the building, rod, and grounding wire for damage.
Lightning rod and glass harmonica
When the glass rod is rubbed with a cloth, it acquires a positive charge by gaining electrons. When the charged glass rod is brought close to the pith ball, the negative charges in the pith ball are repelled, causing the pith ball to become positively charged by induction.
Lightning rod, Franklin stove, bifocals, glass harmonica
Ben Franklin invented a lot of things. one thing that he invented was the glass harmonica. he also invented the lightning rod and bifocal glasses.Also the fire dep.i do not know a$$he taught himself to swim from a book but wanted to be faster so he developed the swim fin. there is the franklin stove there was also a musical instrument with spinning glass to vibrate with your damp fingers think of a glass rim. of course dont forget the lightning rod and bi focals and the idea of ocean currents.

hold a lightning rod up to the sky while lightning is striking
I do not think you would need to insure an lightning rod.
The lightning rod enabled people to have a system that prevented their house from being struck by lightning. It is a metal rod that prevented lightning from striking. Instead of striking the target it bounced off the rod and into the ground.
