This resistor calculator makes it a breeze to calculator resistor color codes. Carbon composition 1/8, 1/4, and 1/2 watt resistors all come in the same basic form factor and have either 4, 5, or 6 color bands. These types of resistor’s value is identified by the color pattern of these bands.
To calculate the resistance of a resistor, you can select the appropriate color bands in the above resistor color code calculator.
