00:00:00,750 --> 00:00:07,750
Today we'll be talking about resistor color codes.

2
00:00:07,750 --> 00:00:13,710
The resistor color code is a system of resistance value marking using color bands.

3
00:00:13,710 --> 00:00:19,170
To read a resistor, orient it so that the color bands are closest to the lead on the

4
00:00:19,170 --> 00:00:22,329
left hand side of the resistor.

5
00:00:22,329 --> 00:00:26,910
The first three color bands show the value of the resistor, while the fourth color band

6
00:00:26,910 --> 00:00:30,190
shows the tolerance or accuracy.

7
00:00:30,190 --> 00:00:35,950
To read the color codes on a resistor, refer to the color code chart in your lab book.

8
00:00:35,950 --> 00:00:38,810
Reading the color decoding chart is quite simple.

9
00:00:38,810 --> 00:00:45,070
As you will see here, the first digit's value is determined by the first stripe of color.

10
00:00:45,070 --> 00:00:50,030
If our first stripe is brown, that gives the first digit a value of 1.

11
00:00:50,030 --> 00:00:55,509
If our second stripe is black, that gives it a digit value of 0.

12
00:00:55,509 --> 00:00:58,630
The third stripe is the multiplier.

13
00:00:58,630 --> 00:01:03,710
On our resistor, our third stripe is yellow, so we simply multiply the first two digits

14
00:01:03,710 --> 00:01:09,010
by 10,000, making this a 100,000 ohm resistor.

15
00:01:09,010 --> 00:01:15,430
The fourth band on this resistor is gold, giving us a tolerance of plus or minus 5%.

16
00:01:15,430 --> 00:01:21,209
And that's how you read the color bands on your resistor.
