Question

Let's consider only the four band resistor where the first two bands give you the significant figures, the third band gives you the multiplier, and the fourth band gives you the tolerance. An example would be a resistor stated to be 140 with an error tolerance of 5%. That is, we expect the value of the resistor to be 140 7 . In this case the color band would be brown, yellow, brown, gold (1, 4, 1, 5%). If we asked you this in a question where you chose the answers in a pull down menu, you would choose the appropriate colors in that order.

a) What is the color band of a 10 resistor with a tolerance of 5%? Select the 4 respective colors

Explanation / Answer

This is very simple color coding problem for resistor,

first two band gives significant digits, third band gives multiplier and last band is for the tolerance.

a)

For 10 ohm resistor, the color code is,

First band - Brown

Second band - Black

Third band - Black

fourth band - Gold

b)

For 22 ohm resistor, the color code is,

First band - Red

Second band - Red

Third band - Black

fourth band - Gold

c)

For 75 ohm resistor, the color code is,

First band - Violet

Second band - Green

Third band - Black

fourth band - Gold

d)

For 1000 ohm resistor, the color code is,

First band - Brown

Second band - Black

Third band - Red

fourth band - Brown(F)
