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.
What is the color code for a 470 ohm resistor?
470 Ohm Resistor Color Code: Yellow, Violet, Brown, Golden.
What does a 470 ohm resistor look like?
So for 470-ohm resistor, 1st digit is ‘ 4 ‘, ∴ look for color in a chart with value 4, then it’s your 1st color(say yellow). The next 2nd digit is ‘ 7 ‘, ∴ look for color in a chart with value 7, then it’s your 2nd color (say violet).
What are the 3 Colour bands of a 470 ohm resistor?
The color code of the 470 ohm resistor is:
- 4 band resistor. yellow – purple – brown – [Tolerance]
- 5 band resistor. yellow – purple – black – black – [Tolerance]
What color is a 47K resistor?
47K Ohm Resistor Color Code: Yellow, Violet, Orange, Golden.
What is the color code for a 20 ohm resistor?
20 Ohm Resistor Color Code: Red, Black, Black, Golden.
What is the color code for a 22 Ω resistor with 20% tolerance?
Red
| Value | First Color | Third Color |
|---|---|---|
| 18* | Brown | 18 k |
| 20 | Red | 20 k |
| 22* | Red | 22 k |
| 24 | Red | 24 k |
What is a 4k7 resistor?
4k7 means that the resistance of those resistors is equal 4.7k ohm (writing the letter K in the middle makes the notation more clear, especially when copied and printed again, so that you don’t have to guess whether it was 4.7k or 47k).
What does 47K resistor mean?
47 multiplied with 1000 is 47000. So this is a resistor with 47000 Ohms (47k Ohms).
What is the color code for a 22 resistor with 20% tolerance?
| Value | First Color | Second Color |
|---|---|---|
| 18* | Brown | Gray |
| 20 | Red | Black |
| 22* | Red | Red |
| 24 | Red | Yellow |

What are 0 ohm resistors for?
Zero-ohm Resistors. A zero-ohm resistor is a resistor that has almost no resistance at all; its resistance is near 0 ohms. A zero-ohm resistor can be wire wound or it can be surface mount.
What is an ohm resistor?
The resistor is a passive electrical component to create resistance in the flow of electric current. In almost all electrical networks and electronic circuits they can be found. The resistance is measured in ohms. An ohm is the resistance that occurs when a current of one ampere passes through a resistor with a one volt drop across its terminals.
