Basics Of Electrical Theory

Electricity is produced when electrons pass through a conductor.

Basics of electrical theory. 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. Key concepts in electrical theory. To apply these concepts have a look at the basic electrical circuits articles to learn about series parallel and other types of circuits and their applications. To jump right in to the theory check out these articles from the basic electrical theory section covering core topics like voltage current and resistance.

March 19 2020 march 19 2020 electricalenergy leave a comment on understanding basic electrical theory. Understanding basic electrical theory. Understanding basic electrical theory. For example a very simple electrical circuit consists of three elements.

The following concepts are foundational to electrical theory. A battery a lamp and an electrical wire that connects the two. The general laws that govern electricity are few and simple but they are applied in an unlimited number of ways. Electrons are subatomic particles that have a negative charge.

No single discovery has affected our lives our culture and our survival more than electricity. We explain concepts like electricity resistance voltage inductors capacitors electromagnetism and more. To comprehend electrical theory you ll have to grasp some basic concepts. So if you know two of the three characteristics your can calculate the third one.

In order to make sense of the code you must first understand basic electrical concepts such as voltage amperage resistance ohm s law wattage circuit theory and others. The fundamental laws of electricity a strong foundation for any electrical worker is built on a thorough knowledge of the laws that govern the operation of electricity. The lower the resistance the easier current will flow. The rules of the national electrical code are written for people who have a pre existing knowledge of electricity.

Circuits can get much more complex consisting of dozens hundreds or even thousands or millions of separate components all connected with conductors in precisely orchestrated ways so that each component can do its bit to contribute to the overall purpose. This series of articles on electrical theory is designed to be a refresher course for the electrical. How much opposition the conductor or metal wire presents to the electric current flow is the electrical resistance. Ohm s law is the basic formula used in all ac and dc electrical circuits.

Ac fundamentals alternating current basic concepts basic electrical fundamentals electrical design protection.
