What does a 470 ohm resistor do?
Introduction: A passive device that resists the flow of electricity. This resistor will provide 470 Ohms of resistance wherever it is placed and will handle 1/4 watts. Use these low value resistors for voltage dividers and where you need to keep the current flow as high as possible.
What color is a 470 ohm resistor?
For example, the color code for the 470 Ω resistor is yellow-violet-brown.
Why are resistors measured in ohms?
Resistance is the measure of electrical “friction” as charges move through a conductor. It is measured in the unit of “Ohm,” that unit symbolized by the capital Greek letter omega (Ω).
Why do resistors have different values?
The standardization of resistor values serves several important purposes. When manufacturers produce resistors with different resistance values, these end up approximately equally spaced on a logarithmic scale. This helps the supplier to limit the number of different values that have to be produced or kept in stock.
What is the color code for a 200 ohm resistor?
Red
| Value | First Color | Third Color |
|---|---|---|
| 20 | Red | 200 k |
| 22* | Red | 220 k |
| 24 | Red | 240 k |
| 27* | Red | 270 k |
What color is a 250 ohm resistor?
250 = Red-Green-Brown.
Which of these color code patterns is found on a 470 ohm 10% resistor?
470 ohm resistor color code for 4-band is calculated as: (1st digit) = Yellow = 4. (2nd digit) = Violet = 7. (multiplier) = Brown = 1 = 10^1 = 10. (tolerance) = Gold= ±5%
What is the real value of 470 ohm resistor?
∴ the real value of 470 Ω resistor is between 446.5 Ω to 493.5 Ω Description: From the resistor code chart we found the color code of resistor with respect to the decimal value of the respective band counted from left to right.
What’s the difference between 330 and 220 ohm resistors?
A 330 ohm resistor with a 20% tolerance will be between 264 and 394 ohms. Did you notice that? At 20% tolerance, there’s a cut off at 264 ohms between 220 ohm resistors and 330 ohm resistors. Likewise, the cut off between 330 ohm and 470 ohm is about 380ohms (about because there’s a bit of rounding in the numbers).
Why do we have the resistor values we do?
This is usually specified on the product. It specifies the degree to which a component can be ‘out’ by. A 220 ohm resistor with a 5% tolerance will be between 209 and 231 ohms. 5% might not be considered that accurate these days (but still easily accurate enough for many uses).
What is the color code for 470 ohm?
The 470 ohm Resistor color code for 4-band is as shown in the image below: [Yellow, Violet, Brown, Gold] 470 ohm resistor color code for 4-band is calculated as: (1st digit) = Yellow = 4
