We know that a resistor is a two-terminal device and is an important component in building many electronic devices. The resistor is a component that is used to limit or regulate the flow of electric current. We commonly see resistors printed with different colours. It usually contains four bands of colours. To know the value of resistors, one must know how to calculate the resistance colour code . In this article, let us learn what is resistance colour code , how to read resistor colour code ... Find out the resistance, tolerance, and temperature coefficient of your resistor component with this online tool. Choose the number and colors of bands, and get the result with formulas and examples. With our resistor colour code calculator, you can get the answer you need in seconds, and without the risk of human error. Simply select the colours from your resistor (whether it’s a 4-band, 5-band, or 6-band resistor), and the calculator will instantly display the resistance value in ohms. Learn how to use the resistor color code to identify the resistance and tolerance of 3, 4, 5, and 6 band axial resistors.
