Blank band is only used with 4 - band code. All 5 - band resistors use colored tolerance band. Colors brown, red, green, blue, and violet are used as tolerance codes on 5 - band resistors only. But when the resistor is smaller, print is too small to read, so specifications must be shown in another way. Generally, resistance value, tolerance, and wattage rating are printed on the body of the resistor as numbers or letters when the resistor's body is big enough to read print, such as large power resistors. Resistor Color Coding uses color bands to quickly identify resistors ' resistive value and its percentage of tolerance with physical size of resistor indicating its wattage rating. Add em on up! So the total resistance of that circuit is: R 1 + R 2 + R 3 | R 4 + R 5 + R 6 |.Ĭomponents and wires are cod with colors to identify their value and function.
#2.2k resistor color code series
And that's just three Series resistors between and B terminals. Then those Series resistors are all in parallel with R 3.

R 4, R 5 and our conglomeration of R 6 - R 9 are all in Series and can be add.

Making our circuit: now four right - most resistors can be simplified even further. Those three resistors are in parallel with R 6, so those four resistors could be turned into one with resistance of R 6 |. In this case, R 7, R 8 and R 9 are all in Series and can be added together. The Tame Resistor network question might be something like: what's resistance from terminals to B in this circuit? To solve such a problem, start at the back - end of the circuit and simplify towards two terminals. As special introduction to calculating total resistance, electronics teachers just love to subject their students to finding that of crazy, convolute Resistor networks.
