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?
- 4 band resistor. yellow - purple - brown - [Tolerance]
- 5 band resistor. yellow - purple - black - black - [Tolerance]
What does a 470 ohm resistor do?
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 is the Colour code of a carbon resistor having a resistance of 470 ohm and a tolerance of 5%?
The colors of a resistance of 470 Ω ± 5% is Yellow, Violet, Brown, Gold.
What color is 470 ohm resistor?
470 Ohm 0.5W Carbon Film Resistor (CFR) with ±5% Tolerance. 470 Ohm Resistor Color Code: Yellow, Violet, Brown, Golden.
What does a higher resistor do?
If you have a constant current source passing through a resistor, then, yes, increasing the value of the resistor will increase the voltage drop across it. Ohm's Law gives the resistance as the ratio of the voltage and current, as R = V/I.
What happens if I use a higher ohm resistor?
When we replace a resistor with a higher value of resistor, the current in the circuit will decrease by an amount depending upon the value of the new resistor. Where E = voltage in the battery/cell and r = internal resistance of the circuit.
What is the use of ohm resistor?
A 1 Ohm resistor is "just another component". It may be used as a current sense resistor or for some other circuit function. If using resistors for current sensing for measurement purposes. Worst case voltage drop across them should be small compared to total circuit voltage so that they do not affect operation.
What is a 470 ohm resistor?
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 does 2k2 resistor mean?
Resistor colors - Red, Red, Red = 2, 2, 2 = 22 and 2 zeros = 2200 ohms = 2.2k, usually written as 2k2.
