What is the primary purpose of a lightning rod installed on tall buildings?
ATo provide a safe, low-resistance path for lightning current to reach the ground
BTo generate electricity from storms
CTo predict when lightning will strike
DTo attract more lightning strikes for research purposes
Explanation
A lightning rod, or lightning conductor, is a metal rod mounted on a building and connected by a cable to the ground, providing a safe, low-resistance path for lightning current to travel if the structure is struck. This directs the powerful electrical discharge safely into the earth rather than through the building’s structure, reducing the risk of fire or structural damage. The concept was famously popularized by Benjamin Franklin in the eighteenth century. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
