Electronics S1W3: Learn to Calculate Watts, Volts and Amps

After Voltage, Current and Resistance, the last component of the Ohm's Law Wheel is Power. This video and the next video explains the basics of power, the fundamental formulas and how to integrate power into the Ohm's Law Wheel.

After Voltage, Current and Resistance, the last component of the Ohm's Law Wheel is Power. This video is Part 2, that explains the basics of power, the fundamental formulas and how to integrate power into the Ohm's Law Wheel.

The Ohm's Law Wheel is a tool for electronics personnel to easily and quickly identify the correct formula or computation to use when solving for unknowns in any electrical or electronic circuit. This lecture explains the Wheel and how to use it properly.

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.

Significant Digits are helpful tools for engineering calculations. This lecture shows you how to determine the number of significant digits in a number.

Most adults are acquainted with round up or rounding down a number. "Rounding to Even" has specific rules, and is a common practice in all engineering professions.
