Ac Electricity For Dummies

Module 9 ac power this module presents power calculations for single phase and three phase ac.

Ac electricity for dummies. If your rig has two ac units it s probably a 50amp rig because you need enough throughput to run both ac units at the same time. The basics of three phase electricity explained. Advertisement the big advantage that alternating current provides for the power grid is the fact that it is relatively easy to change the voltage of the power using a device called a transformer. Three phase electric power is a common method of alternating current electric power generation transmission and distribution.

So if you have a 50a rv but the campground you re staying at only offers 30a you ll need an adapter for the plug that connects the rv to the shore power. We will discuss the following aspects. It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power. Alternating current is used in nearly all the world s power distribution systems for the simple reason that ac current is much more efficient when it s transmitted through wires over long distances.

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. With this method voltage forces electrons to flow first in one direction then in the opposite direction alternating very quickly. Either as a voltage switching polarity or as a current switching direction back and forth this kind of electricity is known as alternating current ac. Typically you ll either see 50 amps or 30 amps.

We start with a simple single phas. Direct vs alternating current whereas the familiar battery symbol is used as a generic symbol for any dc voltage source the circle with the wavy line inside is the generic symbol for any ac voltage source. The voltage generated by utility companies for our home factories and offices is ac. But what is electricity really.

A generator is used to produce ac voltage. All electric currents lose power when they flow for long distances but ac circuits lose much less power than dc circuits. In this video we learn how three phase electricity works from the basics. It is also used to power large motors and other heavy loads.

The power that is available at a wall socket in the united states is 120 volt 60 cycle ac power. Electric charge refers to a fundamental property of matter that even physicists don t totally understand. This module describes the basic concepts of alternating current ac electrical circuits and discusses the associated terminology. This type of voltage is called alternating current ac voltage.

Module 8 ac reactive components this module describes inductance and capacitance and their effects on ac circuits. Please scroll down and start reading. Let s start with three very basic concepts of electricity.
