Basic Electrical Theory For Dummies

Learn basic electrical concepts and terms.

Basic electrical theory for dummies.

Conventional flow electron flow. Long before anyone heard the word electricity people had seen lightning and experienced shocks from electric fish. Let s start with three very basic concepts of electricity. At the most basic level analyzing circuits involves calculating the current.

People depend on electricity constantly and when the power goes out in a storm or there s a tripped breaker or another problem in an electrical circuit understanding the basic components of an electrical system can help you get things running again. The positive to the negative. But what is electricity really. Ohm s law is a key device equation that relates current voltage and resistance.

Suffice it to say that two of the tiny particles that make up atoms protons and electrons are the bearers of electric charge. For an example imagine where the medical field would be without electricity and in that sense how many lives have been. Understanding basic electrical theory. Why should you understand electricity current and amperes potential difference and volts relationship between potential difference and current sources of potential difference concept of resistance ohms law dc and ac current why.

Electric charge refers to a fundamental property of matter that even physicists don t totally understand. When doing circuit analysis you need to know some essential laws electrical quantities relationships and theorems. Learn basic electrical concepts and terms. It s also important to know who is responsible for what portion of your electrical service.

Please scroll down and start reading. Namely electric charge electric current and electric circuit. Understanding electricity even though basic electrical theory was not understood until much later electricity has existed in the world since the beginning of time. This theory states that electrons flow from negative to positive.

We will discuss the following aspects. Circuit analysis for dummies cheat sheet. Ben s theory became the convention hence the term conventional current in electrical theory mathematics textbooks and electrical equipment for the next hundred years.
