How do you calculate resistance color code?
Reading and Determining the Resistor Value Hold the resistor with the gold or silver band to the right and read the color codes from the left to the right. Select the color codes from the bands on the resistor. Read the colors from left to right. The resistance value based on the color code provided is now displayed.
How do you calculate 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.
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%.
What Colour is the third band in a 680 ohm resistor?
| Value | First Color | Third Color |
|---|---|---|
| 62 | Blue | 620 |
| 68* | Blue | 680 |
| 75 | Violet | 750 |
| 82* | Gray | 820 |
What are the colors for a 4 band 470k ohm 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%
How do I identify a 5 band resistor?
For the 5 band resistor:
- Band 1 – First significant digit.
- Band 2 – Second significant digit.
- Band 3 – Third significant digit.
- Band 4 – Multiplier.
- Band 5 – Tolerance.
What do the different colors of resistance bands mean?
– Yellow – The yellow bands are classified as light resistance. – Red – Red resistance bands are medium resistance. – Green – Green resistance bands are medium to heavy resistance. – Blue – Blue resistance bands are heavy resistance. – Black – Black resistance bands have the most resistance.
What do resistance exercise band colors mean?
Best resistance band for pull ups: extra-long pull up band
What is a resistor color band?
Definitions and Calculations. A resistor is a passive electrical component that creates electrical resistance in electronic circuits.
How do you calculate resistor resistance?
Current. When resistors are connected in series,the current through each resistor is the same.
