An electronic color code is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, diodes and others. A separate code, the 25-pair color code, is used to identify wires in some telecommunications cables. Different codes are used for wire leads on devices such as transformers or in building wiring.
A mnemonic to remember the resistor colour code. You can remember the colour code values using the following mnemonic: BB ROY of Great Britain had a Very Good Wife. The capital letters represent the first letters of the colours and their positions the digit values. Now that we have an idea to determine the resistance value of a given resistor.Resistor color code chart. The chart below shows how to determine the resistance and tolerance for resistors. The table can also be used to specify the color of the bands when the values are known.Our Resistor Color Code Calculator is a handy tool for reading carbon-composition resistors whether it's a 4-band, 5-band or 6-band type. To use this tool, simply click on a particular color and number and watch how the actual bands on the resistor illustration change.
Question: Using the colored bands on the two resistors at your table, you determine that the two resistances of the resistors are 300 ohms with 20% tolerance and 200 ohms with a 10% tolerance.
Resistor color code calculator The calculator above will display the value, the tolerance and performs a simple check to verify if the calculated resistance matches one of the EIA standard values. Select the first 3 or 4 bands for 20%, 10% or 5% resistors and all 5 bands for precision (2% or less), 5-band resistors.
This is a chart of resistor color codes. There are basically three types of color band resistors; namely, 4-, 5-, and 6-band resistors. The color helps us know the resistance of the resistor without measuring it.
Color code. Some resistors have color bands which indicate values and their tolerances. You will see 3, 4, or 5 bands around carbon-composition resistors and film resistors. Other units are large so that the values can be printed on them in the ordinary numerals.
To calculate the value of a resistor using the color coded stripes on the resistor, use the following procedure. Step One: Turn the resistor so that the gold or silver stripe is at the right end of the resistor. Step Two: Look at the color of the first two stripes on the left end.
RESISTOR COLOR CODE SYSTEM Resistor color coding system applies to carbon film resistors, metal oxide film resistors, fusible resistors, precision metal film resistors, and wirewound resistors (cylindrical with enlarged ends) of the axial lead type. This system was employed for resistors when the surface area was not sufficient to print the resistance value for the past time. The first 3 (4.
Resistor Color Code Chart and Resistance Calculator. Resistors have standard colors for identification of the resistance value. In order, the colors are: black, brown, red, orange, yellow, green, blue, violet, gray, and white. Reading resistors is a very simple procedure if you use the chart and formula below.
AM I on the Radio? activity—Resistor Color Code Chart Handout 1 Resistor Color Code Chart Resistors are devices that limit current flow and provide a voltage drop in electrical circuits. Because carbon resistors are physically small, they are color-coded to identify their resistance value in ohms. The use of color bands on the body of a.

For Homework 5, you need to compute paths (from the west to the east side of the terrain) that follow the policy of “path of least resistance ”, identify the best of those paths regarding vertical movement. The final output is the image of the terrain (as in Homework 4), now also containing all the paths.
Resistors — devices that have significant drag and oppose current. Pressure will drop across them when current is flowing through them. The resistor shown in the figure is of the kind used in hand-built electrical circuits. The stripes color-code the size of the resistor and its precision. We indicate them with the zig-zag symbol shown on the.
