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:

Example 4. Determine the nominal resistance in addition to tolerance as long as the resistor shown below. Resistor nominal value = 100101 = 1,000 = 1k. – – – 10 – % Tolerance = 2% Solution: Example 5. Determine the nominal resistance in addition to tolerance as long as the resistor shown below. Resistor nominal value = 680103 = 680,000 = 680k. – – – 10 – % Tolerance = 1% Solution: Which side of a resistor do I read from A question that often arises when reading the color code of real resistors is: how do I determine which side of a resistor do I read from Answer: For 4-b in addition to resistors a gold or silver b in addition to is always the last b in addition to . If the resistor has 5 b in addition to s or if there is no tolerance b in addition to (20%), then the first b in addition to is the one located closest to a lead.

Converting the Nominal Resistance in addition to Tolerance into the Color Code We are given the nominal value in addition to the tolerance in addition to we have to come up with the color code. Resistors with 5% in addition to 10% Tolerance will have 4-b in addition to s 4-B in addition to Resistors Convert nominal value to ohms () 1st digit (from left to right) of nominal value = 1st color b in addition to 2nd digit of nominal value = 2nd b in addition to Number of zeros remaining = 3rd (multiplier) b in addition to Tolerance = 4th b in addition to Example 6. Specify the color code of a resistor with nominal value of 27k in addition to a tolerance of 10%. Solution: 2 7 , 0 0 0 2) Convert the nominal resistance value to from k. 1) Since resistor Tolerance = 10% it will have 4-b in addition to s. Example 7. Specify the color code of a resistor with nominal value of 1.5k in addition to a tolerance of 5%. Solution: 1 , 5 0 0 2) Convert the nominal resistance value to from k. 1) Since resistor Tolerance = 5% it will have 4-b in addition to s.

Converting the Nominal Resistance in addition to Tolerance into the Color Code Resistors with 1% in addition to 2% Tolerance will have 5-b in addition to s 5-B in addition to Resistors Convert nominal value to ohms () 1st digit (from left to right) of nominal value = 1st color b in addition to 2nd digit of nominal value = 2nd b in addition to 3rd digit of nominal value = 3rd b in addition to Number of zeros remaining = 4th (multiplier) b in addition to Tolerance = 5th b in addition to Example 8. Specify the color code of a resistor with nominal value of 2.5M in addition to a tolerance of 1%. Solution: 2 , 5 0 0 , 0 0 0 2) Convert the nominal resistance value to from M. 1) Since resistor Tolerance = 1% it will have 5-b in addition to s. Congratulations! You now know how to work with the resistor color code It’s that simple!
