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.

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.
