How do you find the color code of resistance?
Temperature Coefficient
- 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.
- 6th color band is the temperature coefficient of resistance.
What is the color of resistance?
Standard Resistor Values and Color
| Color | Digit | Tolerance (\%) |
|---|---|---|
| Black | 0 | |
| Brown | 1 | 1 |
| Red | 2 | 2 |
| Orange | 3 |
How do you find the resistance value?
Divide the voltage by the current to get your resistance. This formula, known as Ohm’s Law, is a fundamental law of electronics and states that the voltage is equal to the resistance multiplied by the current. For example, a 120 volt circuit that generates 10 amperes of current would have a resistance of 12 ohms.
What is the resistance value of Orange Red Yellow silver?
Resistor #2 has the colors orange orange yellow silver which “translates” into 3 3 ×10,000 or 330,000 ohms and a tolerance of 10\%. Resistor #3 has the colors yellow violet silver meaning 4 7 ×.
What is the resistance value of red violet yellow?
4700Ω
Yellow Violet Red = 4 7 2 = 4 7 x 102 = 4700Ω or 4k7 Ohm.
What is the Colour Code of carbon resistance?
brown
The colour code of carbon resistor is brown is, Brown, Black and Red.
What color is a 330 ohm resistor?
330 Ohm 0.25W Carbon Film Resistor (CFR) with ±5\% Tolerance. 330 Ohm Resistor Color Code: Orange, Orange, Brown, Golden.
What does the third color band is silver mean?
Similar to the 3 band resistor, the first two bands always give the first 2 digits of the resistance value. The third band represents the multiplier while the fourth band represents tolerance. For a 4 band resistor color code, we can begin by first finding the tolerance band as it is usually gold or silver.
