**20+ 3.3 K Resistor Color Code 5 Band Gif**. Resistance = (100×digit + 10×digit + digit)×multiplier. Color bands are used because they can be easily and cheaply printed on a small electronic component.

As a multiplier, it is × 10, so you will calculate 494 × 10; While actually measuring the resistance before using it is a good idea, it is also a good idea to know what the resistance is supposed to be. 5 band resistors are resistors with higher precision, and they have an extra band for a 3rd significant digit.

### The coloured bands are shown as:

They are given by several bands and together they. As a multiplier, it is × 10, so you will calculate 494 × 10; Resistor color codes (5 bands). To use the calculator you need either to choose colors of resistance bands, the color of tolerance band or to enter actual resistance value in the field r (don't forget to choose the proper unit).
