What is electricity

The moment and running of electrons in a specific direction is known as electricity. This moment and running of electrons is from one atom to another atom freely in a conductor or conducting material. Protons are attracting electrons. As we have plenty of electrons on the far end of conductor; many electrons are attracted by protons. This is how electricity flows. This push and pull of electrons and protons is creating a pressure. This pressure is known as voltage in electrical. The other name of the voltage is electro motive force or emf. All generators and batteries are producing emf. The emf forces electrons in the conductor resulting in current. The emf pushes and tending the electrons to flow from the outer orbit of electrons. On the outer orbit of electrons the nucleus has less force of attraction or bonding. These electrons in the outer orbit are known as free electrons. The less the number of electrons in the outer orbit, the more that material will be conductor. The more the number of electrons in the outer orbit of an atom the less that material will be conductor. When an electron is free from its outer orbit, the atom becomes more positive. That atom can take electron from another associated atom outer orbit. This way the flow of electrons stays all the time. The flow of electrons in a conductor is happening in the speed of light. Also we cannot see electricity. But we can feel its effect and also we can measure it using measuring instruments. There are different measuring instruments for different electrical quantities. A voltmeter for example is used to measure voltage. An ampere meter is used to measure current. A watt meter is used to measure electrical power. Electricity is used everywhere in our life. In household, in computer, in communication, in mobile phones, in automotive means everywhere there is a use of electricity. Without electricity one cannot think to live today.
