Basic Electrical Theory For Dummies

The positive to the negative.

Basic electrical theory for dummies.

Suffice it to say that two of the tiny particles that make up atoms protons and electrons are the bearers of electric charge. Conventional flow electron flow. Understanding electricity even though basic electrical theory was not understood until much later electricity has existed in the world since the beginning of time. It lights our way cooks our food and can even brush your teeth.

Understanding basic electrical theory. Please scroll down and start reading. At the most basic level analyzing circuits involves calculating the current. When doing circuit analysis you need to know some essential laws electrical quantities relationships and theorems.

Ohm s law is a key device equation that relates current voltage and resistance. But what is electricity really. For an example imagine where the medical field would be without electricity and in that sense how many lives have been. Namely electric charge electric current and electric circuit.

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. No single discovery has affected our lives our culture and our survival more than electricity. It s also important to know who is responsible for what portion of your electrical service. This theory states that electrons flow from negative to positive.

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. Learn basic electrical concepts and terms. Circuit analysis for dummies cheat sheet. Let s start with three very basic concepts of electricity.

Learn basic electrical concepts and terms. Electric charge refers to a fundamental property of matter that even physicists don t totally understand. Long before anyone heard the word electricity people had seen lightning and experienced shocks from electric fish.
