Defines the term quantity Ampere also Covers Basic characteristics of Resistance and Explains the Color Code System and the Tolerance System for Fixed Resistors  and other  Passive Components that provide Resistance in an Electronic Circuit. This is first step for someone who is entering the field of electronics .

What’s Covered in Series Circuits, Parallel Circuits, & Series Parallel Circuits

This course take the Student thru Calculating Voltage, Current and Resistance on a Series , Parallel  and Series Parallel circuits ! The Instructor give the student a step by step instruction on how to solve these circuit properties. After finishing this course the student should have a very good understanding of Voltage drops , Current Division and Power consumption in a  Electronic  Circuit . Instructor uses ohms law to demonstrate how to find the above Circuit Calculations, The instructor also pushes that the student should have intuitive feeling about the results.

The instructor gives an explanation and examples  on how to find the individual Voltage drops and using Ohms law and the Voltage division method. Instructor also shows and describes how to confirm that the Electronic Principals that were calculated are correct.

The Course will then provide a virtual Electronic Lab , test equipment  here the instructor presents a virtual presentation on how to setup  a circuit of test and evaluation. In this lab the instructor will use the Virtual test pieces (i.e Power supply , Multi Meter and additional  information that will give the Student a real hand on experience.)

This course assumes the the prospected Student has basic Math Skills and can preform basic math functions ( i.e. Addition ,Subtraction Multiplication and Division).

What’s Covered in Advanced Circuit Theory

What are Network Theorems:

Electric circuit theorems are always beneficial to help find voltage and currents in multi-loop circuits. These theorems use fundamental rules or formulas and basic equations of mathematics to analyze basic components of electrical or electronics parameters such as voltages, currents, resistance, and so on

What is Kirchhoff’s Circuit Laws :

Kirchhoff’s circuit laws are two equalities that deal with the current and potential difference (commonly known as voltage) in the lumped element model of electrical circuits. They were first described in 1845 by German physicist Gustav Kirchhoff.

What is Super Position:

The superposition theorem states that a circuit with multiple voltage and current sources is equal to the sum of simplified circuits using just one of the sources. A circuit composed of two voltage sources, for example, will be equal to the sum of two circuits, each one using one of the sources and having the other removed.

What is Thevenin to Norton Conversions

Since Thevenin’s and Norton’s Theorems are two equally valid methods of reducing a complex network down to something simpler to analyze, there must be some way to convert a Thevenin equivalent circuit to a Norton equivalent circuit, and vice versa (just what you were dying to know, right?.

Operational Amplifier Section

Historical Back Ground:

The operational Amplifier was developed for use in Analog Computers in the 1940’s.Early Operational Amplifiers used Vacuum Tubes were large in size and consumed large amount’s of Power.

In 1967 FairChild  Semiconductor introduced the first Integrated circuit Op=Amp. Todays Operational Amplifiers are far super then there Vacuum tube predserors. They are much smaller consume much less power and can be bought  for a few dollars.

Introduction

The Operational Amplifier “(or Op-Amp) is a high Performance Linear Amplifier with an amazing variety of uses. The Op-Amp has two inputs, (-) inverting and (+) and non-inverting and one output. The polarity  of a signal applied to the output. A Signal applied to the non-inverting input retains it’s polarity  at the Output.

The gain of an Op-amp is determined by a feedback resistor that feeds some of the amplified signal from the output to the inverting. This reduces the amplitude of the output signal, hence the gain. The smaller the resistor, the lower the gain.
