Description

The course:

This course is Week One of an Eight Week section titled "DC Electronics", which is the first semester of an eight semester program.

The main topics for this course are:

1. Starting at the atomic level, or, why we need to understand how electricity and electronics are driven by electrons.

2. The three things that make electronics work:

......Conductors

......Insulators

......Semiconductors

3. What is electrical/electronic current?

4. Intro to basic circuit terminology.

5. Overview of many schematic symbols

The Semester: (This course is week 1 of this eight week semester.)

These are the classes for this eight week semester:

1. Direct Current at the Molecular Level (This class)

2. Electrical Units; Volts, Ohms, Amps and Watts

3. Measuring Equipment

4. Basic DC Circuits; Voltage, Current, Resistance and Power

5. DC Circuit Analysis; Kirchhoff's Laws; Determining Resistance, Voltage, Current and Power in Series and Parallel Resistive Circuits

6. Resistors, Potentiometers, and Rheostats

7. Cells and Batteries

8. Magnetism and Magnetic Devices; Selonoids and DC Motors

The Program:

This course is part of the first semester, DC Electronics. Future semesters will include AC Electronics, Solid State Electronics (Transistors, FETs, MOSFETs and JFETs), Transistor and OpAmp theory, Communications Theory and Digital Electronics.

Who this course is for:

This course is appropriate for teens through adults that desire to understand, analyze, design, repair and construct electronic circuits or projects.
People who take electronics courses often go on to become electronics hobbyists, robotics hobbyists, electronics engineers, electronics test technicians or electronics repair technicians.

Course content

4 sections • 16 lectures

Electricity at the Molecular Level 4 lectures

Electricity at the Molecular Level Preview 19:22

At the conclusion of this video:

1. You will have an introductory understanding of the Periodic Table of the Elements.

2. You will be able to name the parts of an atom and the charge (positive, negative or neutral) of each.

Electricity at the Molecular Level

The composition of atoms is reviewed

Charge and Bonding Preview 16:55

At the conclusion of this video, you will:

1. understand charge and that it is a lack or an excess number of electrons.

2. describe how atoms of different elements bond together.

Charge and Bonding

Units of charge and current flow are described.

Conductors, Insulators and Semiconductors 4 lectures

Conductors, Insulators and Semiconductors, Part 1 of 2 Preview 19:58

At the conclusion of this video, you will understand that the number of electrons in the outer shell of any element is what gives that element the ability to conduct electricity.

Conductors, Insulators and Semiconductors

Electronics: Conductors, Insulators and Semiconductors Preview 19:52

At the conclusion of this video, you will understand the fundamental fact that electricity or electronics depends on the movement of charge (electrons) in conductive elements.
