Basic Electricity

Electricity is the flow of electrons from one place to another.

Basic electricity. Single electron in outer orbit. Namely electric charge electric current and electric circuit. The movement of electrons. No single discovery has affected our lives our culture and our survival more than electricity.

Understanding basic electrical theory. Electricity surrounds us and can be used thousands of different ways. In electronics and electrical technology a coil is. Electricity is the movement of electrons.

Electrons create charge which we can harness to do work. This is the currently selected item. Matter can be broken down into. So if you know two of the three characteristics your can calculate the third one.

Electrons can flow through any material but does so more easily in some than in others. Your lightbulb your stereo your phone etc are all harnessing the movement of the electrons in order to do work. Let s start with three very basic concepts of electricity. 120v 60 hz sine wave diagram.

Learn about the basics of electricity from generators and electrical circuits to voltage and currents. Ohm s law is the basic formula used in all ac and dc electrical circuits. Suffice it to say that two of the tiny particles that make up atoms protons and electrons are the bearers of electric charge. When an electric circuit flows through a conductor a magnetic field or flux develops around the conductor.

In this video we learn how electricity works starting from the basics of the free electron in the atom through conductors voltage current resistors led. Electric charge refers to a fundamental property of matter that even physicists don t totally understand. The highest flux density occurs when the conductor is formed into a coil having many turns. There are two changes in polarity and two changes in current direction per cycle.

Analyzing a resistor circuit with two batteries. Current flows in both directions. How easily it flows is called resistance. But what is electricity really.

The resistance of a material is measured in ohms. Electrical designers use it to determine how much voltage is required for a certain load like a motor a computer or even a house full of appliances. They all operate using the same basic power source. Analyzing a more complex resistor circuit.
