How did Benjamin Franklin discovered electricity||The origin of electricity

In 1748, Franklin, then 42 years old, had expanded his printing business throughout the colonies and become successful enough to stop working. Retirement allowed him to concentrate on public service and also pursue more fully his longtime interest in science. In the 1740s, he conducted experiments that contributed to the understanding of electricity, and invented the lightning rod, which protected buildings from fires caused by lightning. In 1752, he conducted his famous kite experiment and demonstrated that lightning is electricity. Franklin also coined a number of electricity-related terms, including battery, charge and conductor.

In addition to electricity, Franklin studied a number of other topics, including ocean currents, meteorology, causes of the common cold and refrigeration. He developed the Franklin stove, which provided more heat while using less fuel than other stoves, and bifocal eyeglasses, which allow for distance and reading use. In the early 1760s, Franklin invented a musical instrument called the glass armonica.
