Alessandro Volta was so fascinated by electricity that, as a student, he even wrote a poem about it. As an adult, he created an electric battery by putting moisture between zinc and copper disks.
A battery stores energy and makes it available when needed as electricity. The battery led to such inventions as the telegraph and the telephone. Today, cars, cell phones, laptops and most portable gadgets depend on batteries. And the battery has inspired people to invent other energy-storing devices, such as solar panels.
For changing the world, a unit of electricity called the “volt” was named after Volta.
