The 4- and 5-band resistors are frequently used, on w hich there are 4 and 5 chromatic bands.

Let’s see how to read the resistance value of a 5-band resistor as shown below. Normally,

when you get a resistor, you may find it hard to decide which end to start for reading the

color. The tip is that the gap between the 4

and 5

band w ill be comparatively larger.

Therefore, you can observe the gap between the two chromatic bands at one end of the

resistor; if it's larger than any other band gaps, then you can read from the opposite side.

So for this resistor, the resistance should be read from left to right. The v alue should be in this

format: 1

Band 2

Band 3

(Ω) and the permissible error is ±Tolerance%. So

the resistance value of this resistor is 2(red) 2(red) 0(black) x 10^0(black) Ω = 220 Ω, and the

permissible error is ± 1% (brow n).

One more example. The resistance of the resistor below should be 1(brown) 0(black) 0(black)

x 10^1(brown) Ω =100x10 Ω = 1000 Ω = 1KΩ, and the permissible error is ± 1%(brown). Now try

it by yourself!

Now let’s try a 4-band resistor. There are two 4-band resistors in the kit: a 1MΩ one and a

5.1MΩ one. You may not use such a large resistor in the experiments of the kit but you can

use them in other projects. Unlike 5-band resistors, the third band of a 4-band one is not the

band but the multiplier; its fourth band is Tolerance. So the resistance v alue of a 4-band

resistor should be 1st band 2nd band x 10^Multiplier (Ω), and the permissible error is

±Tolerance%.
