What is the value in ohms of a resistor colored brown red yellow gold?
The first band, brown, indicates the digit 1.The second band, red, indicates the digit 2.The third band indicates the multiplier. For yellow, this is 10000.12x10000 = 120,000 ohms.The last band is an indication of the tolerance of the resistor; gold means the actual value is within 5% of the stated value.
What do the colours on resistor mean?
The colored bands on a resistor represent the resistor value and tolerance. The first two bands indicate the significant digits of the resistance value, the third band represents the multiplier, and the fourth band (if present) indicates the tolerance of the resistor. By decoding these colors, you can determine the resistance value of the resistor.
What do the first 3 bands on a resistor indicate?
The first 3 band on a resistor indicate the value of that resistor.
How do you add up the restience of the coloured bands of a resistor?
To determine the resistance value of a resistor using its colored bands, first identify the colors of the first two bands, which represent the first and second significant digits. The third band indicates the multiplier (the power of ten by which to multiply the combined digits). For example, if the first two bands are red (2) and green (5), and the third band is brown (10^1), the resistance would be 25 x 10 = 250 ohms. If there is a fourth band, it usually indicates tolerance.
How can you find a resistance of resistor without DMM explain the method with the help of example?
Hi You can find the value of the resistor by using colour code printed on the resistor. 1. Hold the resistor such that the colour code starts from left. 2. Each of the colour bands present on the resistor specifies a value. 3. The first colour band represents the first significant figure, the second band represents the second significant figure and the third band indicates the multiplier. The fourth band represents the tolerance. Gold band- 5%, Silver band-10%, No band-20% 4.Find the appropriate values for the colour by using the chart 1. 5. Find the value of the resistor by using the formula 1. Chart1 Example: Here first band represent brown. Second band represent black. Third band represent red . Fourth band represent gold. The value of resistor = 10 x 102 ± 5% = 1kΩ ± 5%
What value is resistor that is colored white white white brown?
When a resistor has a 4th color band, its color is either gold or silver, so I will assume the color bands are white-white-white-gold. The resistance is 99 GΩ ± 5%.
What is the number value of a green band in the first first position on a resistor?
The answer is 5, the question originates from CDX
What is the function of the tolerance band on a fixed resistor?
A: Not all application need close tolerance of values some application only need 5% and some 10% so the band is there to specify the -/+ % tolerance that the part is in compliance with. Designers decide what parts % is needed for proper performance of the circuit.
What do the lines on the resistor mean?
They are color coded lines (or Bands) that are usually broken down into 2 parts. the first part of the bands are to establish the amount of resistance the resistor is constructed, by design, to perform in a circuit. The second part (which is the usally the last line or band) extablishes the amout of tolarance the designed resistor has. tolorance bands are always silver or gold if they are there but there is a provision where you may not see a tolorance band. There are plenty of electronis sites that can break down the color codes for you. but they are based on a X10, X100, X1000... mutipliers depending on which position the band is located in ie. first, second, third and so on... and for how many there are.
What do the first three bands help determine on a resistor?
The first three bands on a resistor tell you what its resistance is. The first band is the first digit, the second band is the second digit, and the third band is the number of zeros to add. Use the resistor color code to convert... 0 Black 1 Brown 2 Red 3 Orange 4 Yellow 5 Green 6 Blue 7 Violet 8 Grey 9 White As an example, a 27000 ohm resistor would be Red - Violet - Orange. If the third band is Silver, the multiplier is 0.1 and, if the third band is Gold, the multiplier is 0.01. For example, a 0.39 ohm resistor would be Orange - Gray - Gold.
Can you replace a 5 band resistor to a 4 band?
yep
What is the 4th colour band on a resistor?
