A Brief Introduction to Electricity
In order to better understand how solar power works, you must first have a basic understanding of electricity and all that is related to it, such as current, voltage, energy and power. Once you have grasped the basics of electricity, you will better understand how solar power systems function, which will further increase your confidence as you go about the task of determining the right choices and resources for installing an appropriate solar electric system for your home, office or business.
A good understanding of the basics of electricity is crucial to the correct implementation of a good solar power system.
What comes to mind when you hear the term electricity? Perhaps you visualize a type of battery that stores electricity, towering electric pylons transmitting power across the land, or huge electric power stations. Or you may consider the simple, everyday home appliances like the electric iron or coffee pot.
The term “electricity” covers a wide range of physical effects that are related, yet distinctly unique. When you apply more exact terms to electricity, you get a clearer view and understanding.
Electric charge
Another term for electricity would be an electric charge, which is an amount of electrical energy that has built up, such as that found in static electricity, or that travels through a lightning bolt. A coulomb (C) is the usual measurement for this type of charge. Batteries also store electric charge.
Electric current
Electricity can also be known as electric current, which refers to the electric charge flowing through a cable, measured in amperes.
Electric potential
This type of electricity refers to the possible difference between the electrical energy at the positive and negative points in a medium, such as a battery. The electric potential measurement is volts. The principle for electric potential is usually, “the higher the voltage, the more electricity.”
Electromagnetism
Another term for electricity is electromagnetism. This refers to the relationship that exists between magnetism and electricity. This type of electrical energy is usually generated from another type of energy called mechanical energy, like that produced by a generator. Mechanical energy can also be generated from a motor in the form of electrical energy.
