Despite our familiarity with its effects many people fail to understand exactly what electricity is a ubiquitous form of energy resulting from the motion of charged particles like electrons. In this article we ll be learning the basic concept behind how electricity works according to classical theory.
We ll cover atoms electrons protons neutrons then move onto the difference between conductors and insulators wires and cables circuits volts and voltage currents and amps resistors resistance and ohms.
How does electricity work. Electricity is usually sold by the kilowatt hour 3 6 mj which is the product of power in kilowatts multiplied by running time in hours. Each electron has a small negative charge. Suffice it to say that two of the tiny particles that make up atoms protons and electrons are the bearers of electric charge.
How static electricity works electricity is caused by electrons the tiny particles that orbit around the edges of atoms from which everything is made. Electric utilities measure power using electricity meters which keep a running total of the electric energy delivered to a customer. In this tutorial we will learn what electric charge and current is and how electricity works find more on my website.
Electric charge refers to a fundamental property of matter that even physicists don t totally understand. But what is electricity really. Continuing the series on the power grid by diving deeper into the engineering of large scale electricity generation the importance of electricity in our mode.
The atoms with a loose hold on their electrons are best at conducting an electrical current. Let s start with three very basic concepts of electricity. When put to the question even acclaimed inventor thomas edison merely defined it as a mode of motion and a system of vibrations.
Some atoms hold their electrons close to the nucleus and some don t. The process of electricity begins when energy from light heat or magnetic fields stimulates an atom s electrons making them move. How does electricity work.
Namely electric charge electric current and electric circuit.
