Question

In the lightning conductor, what provision is made for spreading the electricity into the ground?

Answer 1

• The lightning conductor consists of a long copper strip with one end forked.
• This end is at the highest part of the building.
• The other end of the strip is connected to a plate of cast iron.
• A pit is dug in the ground, coal and salt are filled into the pit and the iron plate is placed upright in the pit.
• There is also a provision for pouring water into it.
• This helps to spread the electric charge quickly into the ground.
