IDT Energy is a supplier of electricity and natural gas to customers in New York. But electricity does not only effect our lives through the outlets in our homes. Today we have become more and more dependent on our ability to take electricity with us everywhere.VoltaBattery

Batteries are an amazing invention. They allow us to use electric devices while on the go, giving incredible freedom and power to the user. But have you ever thought about how batteries work? Or when they were first used? Interestingly, the first battery dates to the beginning of the 19th century, and was created by Alessandro Volta. Volta was an Italian physicist, born in 1745 in Como, and taught in public schools there. In 1774 Volta became a professor of physics at the Royal School in Como, and a professor of experimental physics at the the University of Pavia in 1779. Volta held this position for 25 years. Because of Volta’s experiments with electrical capacitance the unit of electrical potential has been named in his honor, which of course is known as the volt. Alessandro Volta is credited with creating the very first electrochemical cell, or battery. It was made from two electrodes; one made from the metal zinc, and the second from copper. Sulphuric acid was used as the electrolyte, or salt and water can also be substituted for the acid. This early, primitive battery is still used today as a way to demonstrate to students the principles of electricity. It is referred to as a Lemon Battery.
