Rutten, Tim, Features Columnist has reference to this Academic Journal, PHwiki organized this Journal Underst in addition to ing the Resistor Color Code Dr. Deb Hall Electronics Engineering Technology Valencia Community College Resistor Color Code Manufacturers typically use a color b in addition to system known as the resistor color code Within this power point, you will learn how to identify the nominal resistance in addition to the tolerance of a resistor Resistor Color Code The power rating is not indicated in the resistor color code in addition to must be determined by experience using the physical size of the resistor as a guide. For resistors with 5% or 10% tolerance, the color code consists of 4 color b in addition to s. For resistors with 1% or 2% tolerance, the color code consists of 5 b in addition to s.

4-B in addition to Resistors The resistor nominal value is encoded in the color code in Powers of Ten Notation. The template as long as determining the nominal value in addition to tolerance of a resistor with 4 color b in addition to s is given below: How do we know which color corresponds to which number Answer: Using the Resistor Color Code Table Example 1. Determine the nominal resistance value in addition to the tolerance as long as the resistor shown below. Solution: Nominal value = 10102 = 1,000 Tolerance = 5%. – – 10 – %

It is typical to express the resistance value in: k if the resistance 1,000 M if the resistance 1,000,000. To convert from to k, to M, or vice-versa, use the table below: Example 2. a) Determine the nominal value in addition to tolerance as long as the resistor below. b) What is the minimum resistance value this resistor can actually have c) What is the maximum resistance value this resistor can actually have Solution: – – 10 – % Resistor nominal value = 47103 = 47,000 = 47k. Tolerance = 5% Solution: continued Minimum resistance value: Multiply the nominal value by the tolerance in addition to then subtract this from the nominal value: Maximum resistance value: Multiply the nominal value by the tolerance in addition to then add this to the nominal value:

Example 3. a) Determine the nominal value in addition to tolerance as long as the resistor below. b) What is the minimum resistance value this resistor can actually have c) What is the maximum resistance value this resistor can actually have Solution: – – 10 – % Resistor nominal value = 39105 = 3,900,000 = 3.9M. Tolerance = 10% Solution: continued Minimum resistance value: nominal value  nominal value tolerance: Maximum resistance value: nominal value + nominal value tolerance: 5-B in addition to Resistors For resistors with 1% or 2% tolerance, the color code consists of 5 b in addition to s. The template as long as 5-b in addition to resistors is:
