Resistor Color Codinguses colored bands to quickly identify a resistors resistive value and its percentage of tolerance with the physical size of the resistor indicating its wattage rating. Generally, the resistance value, tolerance, and wattage rating are printed on the body of a resistor as number...
Example for calculate the resistor color code: (Band 1) (Band 2) X (Band 3) with tolerance of Band 4 Consider yellow (4), violet (7), orange (1000), gold (+/- 5%) so the value of resistor is 47K ohm with +/- 5% tolerance. Comments are closed....
Resistor color-coding scheme. Note that not all resistors have the same number of bands, so it is important to know the type of resistor at hand. If a resistor has only four bands, then it does not have the third digit. A few examples are illustrated in Table 6.1. Table 6.1. Example...
For example, if your voltage is 12 volts and your desired resistance is 8 ohms, then the current through your fusible resistor would be 1.5 amps (V = 12 volts; R = 8 ohms; I = V/R = 1.5 amps). Fusible Resistor Color Code Queen Mao’s resistor color coding system was simply applie...

Most chip resistors are marked with a 3-digit or 4-digit code -- the numerical equivalent of the familiar color code for through-hole components. Recently, a new coding system (the EIA-96) has appeared on precision SMDs. The 3-digit code...
