Electronics S1W4: Metric Prefixes and Resistor Color Codes

Correctly use metric prefixes, identify resistor values, measure voltage, current and resistance and circuit power.
4.8 (16 ratings) Instead of using a simple lifetime average, Udemy calculates a
course's star rating by considering a number of different factors
such as the number of ratings, the age of ratings, and the
likelihood of fraudulent ratings.

Curriculum

Section 1: Introduction to Metric Units
18:58

After this lesson, you will be able to identify the metric prefixes and understand how they are used. For example, you will know the difference between milliamps and microamps, or between megavolts and kilovolts.

Metric Prefixes Quiz
5 questions
Section 2: Resistor Color Codes
15:34

Using the color code chart provided, you will be able to look at any resistor that has the color band codes, and determine the exact value of that resistor.

09:53

By using the Color Code Chart provided in lecture 2, you will be able to practice using the code to correctly identify the value of resistors.

Section 3: Types of Resistors and Resistor Power Ratings
17:19

Resistors come in many shapes, sizes and power ratings. This lesson will introduce you to the variations of available resistors.

19:41

When we say that a resistor has a power rating of 1/8 Watt or 1 Watt, what does that mean? This lesson will explain that for you.
