Try Udemy for Business- 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.

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

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.

- 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.

After your previous introduction to Ohm's Law, it is now time to solve basic problems in electronics. The Ohm's Law Triangle is a simple tool used to help beginners remember the relationships between Voltage, Current and Resistance, and to use the triangle to solve an Ohm's Law problem when any two of the three are know.

Ohm's Law states that "current in a circuit is directly proportional to the voltage and inversely proportional to the resistance. This lecture will create a graph for the student that clearly shows the proof of these two relationships, and shows the difference between direct and inverse proportion.

Scientific Notation is a standardized way of writing very large or very small numbers. This, and the next, video will show you how to accurately convert numbers from Standard form (e.g. 94,000,000,000) to Scientific Notation (e.g. 9.4E10) and the reverse: How to Convert Scientific Notation into Standard form.
