Introduction to Electricity

The first lesson uses animation to demonstrate atomic structure, electricity, and how a simple circuit operates. The lesson also explains the characteristics of good conductors and insulators.

Basic Electrical Properties

The second lesson covers Ohm’s Law, as well as the use of Ohm’s Law to calculate an unknown value. The lesson also defines voltage, current, resistance, and power.

Series Circuits

The third lesson covers the identification of simple schematic symbols used to represent components in a series circuit. The behavior of current, resistance, and the use of Kirchhoff’s Voltage Law are also covered.

Parallel Circuits

The fourth lesson describes the behavior of voltage, current, and resistance in a parallel circuit. The learner is also instructed in the identification of the series and parallel portions of a series-parallel circuit.

Alternating Current

This is the fifth lesson teaches the basic AC characteristics of voltage, including how voltage changes over time. The participant is also instructed in using sine waves to interpret the frequency of AC voltage.

Electromagnetism

This sixth lesson uses animations and demonstrations to explain the principles of magnetism, including flux density and electromagnetic induction. The lesson also shows how to plot a sine wave using a graph.

Inductance

The seventh lesson lesson builds on the information presented in the lesson, Electromagnetism. Types of induction, phase, and the effect of induction in AC circuits are covered.

Capacitance

The eighth lesson explains capacitors, their function, and how capacitance affects AC circuits.

Three-Phase Circuits

The ninth lesson lesson defines 3-phase AC, describes the components and operating principle of 3-phase generators, and using the formula for frequency, shows how rotor speed and the number of poles is related to frequency.

Wye and Delta Connections

The tenth lesson discusses Wye and Delta configurations and explains the relationship between phase and line voltages in various connections, and demonstrates the application of the formula that shows this relationship.

Introduction to Transformers

The eleventh lesson presents the basic parts of a transformer and their function. The lesson explains turns ratio and its relationship to a transformer’s input and output voltages.

Transformers

The final lesson builds on the information presented in the lesson, Introduction to Transformers. How to determine primary current and voltage, secondary current and voltage, and load is taught.
