Who Invented the First Electric Battery?
When we talk about electric batteries, we often talk about voltage. But did you know that this word is named after the person who invented the first electric battery? First, let’s take a look at what a volt is, and then we’ll find out more about the guy who gave the ‘volt’ its name.
What is a Volt?
A volt is defined as a unit of electric potential and electromotive force, and voltage refers to the number of those units. That sounds a lot more complicated than it is! If you think of the water in a tap being like the electricity running through a wire, the voltage means the amount of pressure. This video is quite long but explains it very well.
Why are Volts Called Volts?
Alessandro Volta
The term actually comes from a name. It was coined in honour of Italian physicist Alessandro Volta, who is recognised as the inventor of the first electric battery. During the 1790s, Volta worked on the theories of electricity of the day.
Volta disagreed with the theory proposed by fellow Italian scientist Galvani that electricity was generated by animal tissue. Instead of experimenting on frogs or other animals, Volta did experiment after experiment with metals.
His persistence paid off, and in 1800, he invented the world’s first battery, known as the ‘voltaic pile’.
The Voltaic Pile
This voltaic pile was simple but ingenious. It consisted of a pile of zinc and silver discs. But alternating between them was a piece of cardboard, or a piece of cloth, that had been soaked in saltwater.
There was a wire that connected the zinc disc on the bottom to the silver disc on the top, and this wire was capable of producing sparks.
What else Did Volta Invent?
The invention of the first electric battery brought Volta the most fame and recognition, but he also made other discoveries. He invented the electrophorus, a device that could transfer an electrical charge to other objects, as well as an electrical condensor, and the voltaic cell.
He is also known for having discovered and isolated methane gas. After his death, the volt and voltage were named in his memory.
What about Galvani?
Luigi Galvani
Yet there is one more twist to the tale. Volta’s longstanding colleague Galvani of the animal electricity theory also left his name in our language. When we say ‘galvanise’ or ‘galvanism’, that is where it comes from.
Despite their differing theories, there was no rivalry between the two scientists. They were both more concerned with the pursuit of knowledge than with whose theory would prove to be right, and it was Volta who first coined the word ‘galvanismo’ in Italian.

The Doncaster Book Awards – By Kids for Kids
There are lots of children’s book awards, but the Doncaster Book Awards is special. That’s because children decide not only which books they want to win, but even which ones are on the shortlist.
Doncaster is in Yorkshire, in the north of England. Lots of schools in the area, alongside many home-educated kids, register and take part in the awards. First, the children select the shortlist for different categories of books, and these are then voted on by all the schools and the children. Sometimes book publishers ask to get their books on the list, but the answer is always no. This one is by children, for children!
Alice Gives Advice – Written By You
Alice M is 10 years old, and has some great advice on being a girl
The Joy about being a girl is you get more opportunities because people mostly trust girls better than boys. I know that it majorly sexist but technically that is what happens in life.
We all know that girls have to go through a HARD time when they are older but it is sometimes worth it, GIRLS are the ones that actually produce the baby, GIRLS are the ones who have super fashion sense and are the ones who are unique with any kind of style Goth, jumpy, and get have any personality they want to and we wear make-up to make ourselves look nice, scary, horrible anything you want, we can style hair, have fun and mess around.
Some people don’t like being girls mostly because their scared, I am too, but if you think about it there generally is nothing to be afraid of. You have people all along the way to help you enter adulthood and become bigger and better, people will help you when it is hard and when you need constant monitoring but after all that has passed, I will guarantee that you will have had the time of your LIFE being a girl.
So what I am trying to say is: enjoy being a girl, enjoy having horrid things done to you (I know that sounds backwards but trust me, it I’ll be worth it) because when that is all over you’ll miss it.
