How do you read a color band resistor?
Always read resistors from left to right. – Resistors never start with a metallic band on the left. If you have a resistor with a gold or silver band on one end, you have a 5% or 10% tolerance resistor. Position the resistor with this band on the right side and again read your resistor from left to right.
How do you calculate resistor color code?
In 6 band color resistor, each band denotes like the following.
- 1st color band is the first significant digit.
- 2nd color band is the second significant digit.
- 3rd Color Band is the third significant digit.
- 4th color band is Multiplier with a power of 10.
- 5th color band is tolerance.
How do you read a resistor value 3 band using the resistor color code?
For a 3-band resistor color codes, the first two bands always denote the first two digits of the resistance value while the third band represents the multiplier. In the example we have, the bands are brown, black and brown. The first band is the brown band closest to the edge.
What are the color bands on a resistor?
The four band color code is the most common variation. These resistors have two bands for the resistance value, one multiplier and one tolerance band. In the example shown here, the 4 bands are green, blue, red and gold. By using the color code chart, one finds that green stands for 5 and blue for 6.
How do you read a 5 band resistor color code?
If the colors on a 5 band resistor is in this order: brown, green, red, blue and violet (as shown in figure). The values of color bands will be like this: Brown = 1, Green = 5, Red = 2, blue = 106, Violet = 0.10%.
How do you read a three band resistor color code?
How do you calculate the value of a 4 band resistor?
4 band resistor By using the color code chart, one finds that green stands for 5 and blue for 6. The third band is the multiplier, with red representing a multiplier value of 2 (102). Therefore, the value of this resistor is 56 · 102 = 56 · 100 = 5600 Ω. The gold band means that the resistor has a tolerance of 5%.
How do you find the value of 4 band resistors?
The fourth band (or 5th for the 5-band and 6-band) indicates the tolerance values. Here, two colors are added (gold and silver). The 6th band for a 6-band type resistor is the temperature coefficient….Resistor Band Colors.
| Color | Value |
|---|---|
| Yellow | 4 |
| Green | 5 |
| Blue | 6 |
| Violet | 7 |
How do you read a 3-band resistor?
What if a resistor only has 3 bands?
Resistor Color Bands The 3-band resistor has three colors with multiplier and no tolerance. The three bands can be selected to know the resistor value. Whereas, the 4 band, 5 band, and 6 band resistors have an extra band known as tolerance.
What is the equation for a resistor?
Ohm’s law formula. The resistor’s current I in amps (A) is equal to the resistor’s voltage V in volts (V) divided by the resistance R in ohms (Ω): V is the voltage drop of the resistor, measured in Volts (V). In some cases Ohm’s law uses the letter E to represent voltage.
What color is a 10K resistor?
A 10kΩ resistor has brown, black, and orange stripes in that order. The last stripe represents the tolerance. Gold means ±5%. Buy these resistors from Amazon, Adafruit , and Newark .
What are the colors of resistance bands?
Depending on the brand of resistance band, the most common colors include yellow, green, red, blue, black, silver and gold, with yellow being the lightest and gold the strongest. That said, you can also find tan, silver and gold.
What is the standard value of a resistor?
Typical resistor values lie in the range from 100 &OHgr to 10 k&OHgr with a matching tolerance of ±0.2% and a temperature coefficient of resistance of ±10 to ±200 ppm/°C. Diffused resistors are based upon the same fabrication geometry and techniques used to produce the active transistors on the silicon chip or die.
