1a : a fundamental form of energy observable in positive and negative forms that occurs naturally (as in lightning) or is produced (as in a generator) and that is expressed in terms of the movement and interaction of electrons. b : electric current or power.
Whats does electricity mean?
Electricity, phenomenon associated with stationary or moving electric charges. Electric charge is a fundamental property of matter and is borne by elementary particles. In electricity the particle involved is the electron, which carries a charge designated, by convention, as negative.
What is another meaning of the word electricity?

What is electricity made of?
Electricity is the flow of electrons. All matter is made up of atoms, and an atom has a center, called a nucleus. The nucleus contains positively charged particles called protons and uncharged particles called neutrons. The nucleus of an atom is surrounded by negatively charged particles called electrons.
What are two types of electricity?
There are two kinds of current electricity: direct current (DC) and alternating current (AC). With direct current, electrons move in one direction.
Do we need electricity?
Electricity is a form of energy and we need it for just about everything! Almost all of our modern conveniences are electrically powered. Electricity is what lights up our classrooms, heats our homes and lets us listen to our favourite music. You are using electricity right now by using your computer to read this.
How do you generate electricity?

What is the verb of electricity?
electrify. (transitive) To supply electricity to; to charge with electricity. (transitive) To cause electricity to pass through; to affect by electricity; to give an electric shock to.
How does an electricity work?
Electricity works by getting a bunch of conductor elements together and creating a flow of electron-stealing patterns through them. This flow is called a current. Conductors need to be surrounded with insulators so the electrons can only go in one direction. … This is essentially how electricity works.
