What Will I Learn?

- At the end of this course, students will be able to:
- Properly use the Ohm's Law Triangle.
- Understand the relationship between Watts and power.
- Be able to use the Ohm's Law Wheel to solve electronics problems whenever two of the four circuit measurements are known.
- Understand the difference between direct and inverse proportionality.
- Be able to convert very large and very small numbers into Scientific Notation.
- Correctly identify the number of significant digits in any number.

Requirements

- Students need no prerequisite knowledge for this course except basic math, including addition, subtraction, multiplication and division.

Description

You will become proficient in using the basic tools to perfore necessary calculations in the analysis of an electronic circuit. You will use given quantities of volts, amps, ohms or watts to calculate the other characteristics of simple electronic circuits. To do this, you will be taught the proper use of a tool called the Ohm's Law Wheel.

Additional topics include Watts and Power, Scientific Notation, Significant Digits and Rounding Off numbers. This will introduce you to how electronics professionals, hobbyists and engineers deal with the mathematics of electronics.

This course provides you with eleven video presentations lasting more than 2-1/2 hours.

Who is the target audience?

- This course emphasizes the use of simple tools; the Ohm's Law Triangles and the Ohm's Law Wheel, to accurately calculate any of the characteristics such as voltage, current, resistance or power in an electrical or electronic circuit. Students, hobbyists and those thinking of a career in electronics will all find benefits in learning how electronic circuits work.
- Additional topics for this class include: Watts and Power, Scientific Notation, How to identify significant digits and how to correctly round off numbers.
