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 is the voltage drop running through resistor 1 resistor 1 equals 3 ohms?
There is insufficient information in the question to answer it. You need to provide either the voltage across the resistor, or the power dissipated by the resistor. please restate the question.
Colour pattern of resistance?
The color pattern of the primary bands on a resistor are black, brown, red, orange, yellow, green, blue, violet, grey, white - representing 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
How do you place 3 resistance to get the total resistance of 1 ohm?
It depends on the resistance of each resistor. If each resistor, for example, is 0.333 ohm, then you could connect them in series. If each resistor, for example, is 3 ohms, then you could connect them in parallel.
Importance of color coding in carbon resistor?
color coding of resistor:black,brown,red,orange,yellow,green,blue,voilet,grey,white these colors are ranked as:0,1,2,3,4,5,6,7,8,9 tolerance:silver,gold,no color ratings:5%,10%,20%
What are the first 3 bands of a 2.2K resistor?
all 3 red
How many resistor colors BANDS ARE THere?
3 to 6 depending on precision and temperature characteristics.
What do the coloured bands of the resistors mean?
They are a standard code with each individual colour representing a single whole number (1-10) indicating the resistance or ohm value. Additionally the gold band represents 5% "tolerance" and the resistance value is more precise. The silver banded resistors have only 10% tolerance & therefore are not as precise in ohm value. Such should be cheaper to buy than the gold ones.
What does the third and of a resistor mean?
That depends on the resistor, the resistors that are color coded come with either 4, 5 or 6 bands. On resistors with 4 bands, the 3'rd band is the multiplier. F.ex if we have a Resistor colored brown:red:orange it would mean 1 : 2 : 3 which translates to (10+2)*10^3, or 12*1000 = 12k Ohm On resistors with 5 or 6 bands, the 3'rd band is just another digit For examle a 5-band resistor starting with brown|red|orange|yellow would mean 1 | 2 | 3 | 4 which translates to (100+20+3) * 10^4 or 123*10000 = 1,23M Ohm
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.
How do you determine the resistance of a resistor color code black orange orange?
The values and colours of the bands are as follows (0) Black (1) Brown (2) Red (3) Orange (4) Yellow (5) Green (6) Blue (7) Violet (8) Grey (9) White The first two bands are the value, the third is the multiplier (times ten). So as an example if the first band is Red, the second is Green, and the third is Orange, the value would be 25000 or 25k Ohms.
What do the colors on a resistor mean?
Most resistors have either 3 or 4 color bands. The fourth, if it is there, only indicates the tolerance, or how accurate the value is. For the first three bands, the following colors may be used: black = 0 or X1 brown = 1 or X10 red = 2 or X100 orange = 3 or X1000 yellow = 4 or X10000 green = 5 or X100000 blue = 6 or X1000000 violet = 7 gray = 8 white = 9 A resistor uses the first two color bands to form a 2 digit number, then a third band to add a multiplier. For instance, suppose you have a resistor that has a red, violet, brown color code. Decoding: red = 2 violet = 7 27 brown = X10 27 * 10 = 270 In this case, you are holding a 270 ohm resistor. How about a 2.2K resistor? Well, K = 1000, so 2.2K is the same as 2200 ohms. Reverse decoding: The first two bands would have to be red, red (22). To get to 2200 from 22 we have to multiply by 100, so the third band would also be red (X100). The last, or fourth band indicates how close to the nominal value the resistor is. The band colors are: none = 20% silver = 10% gold = 5% So, if the 2.2K resistor is red, red, red, silver, it means the actual resistance can be as much as 10% (or 220 ohms) higher or lower than 2.2K, or anywhere from 1980 ohms to 2420 ohms. You can get resistors with better accuracy than 5%, such as 2%, 1%, 0.1%. Some use three number bands and a fourth multiplier band, others have no bands at all, just the actual resistance printed as a number on the body. If in doubt, measure the resistor with an ohmmeter to be sure.
How do you determine the tolerance of 4-band resistors?
Look at the 4th band:silver, 10%gold, 5%brown, 1%red, 2%orange, 3%yellow, 4%A resistor with only 3 bands is 20%
A resistor may have four coloured bands on it. What does each of these bands indicate?
The first band on the left is the first significant figure.The second band is the second significant figure.The third band is the decimal multiplier.The fourth band, if present, indicates the tolerance in percent. If there is no band, the value means 20%.The resistor in the image above is red, red, yellow, silver or 3, 3, 4 zeros, 10% or 330K ohm 10%. Precision resistors or resistors with unique temperature properties can have as many as six bands:The first band on the left is the first significant figure.The second band is the second significant figure.The third band is the third significant figure. (optional if non-precision)The fourth band is the decimal multiplier.The fifth band indicates the tolerance in percent.The sixth band is the temperature coefficient code. (a special table is needed to interpret this band's color)
Can someone tell me what value this resistor has?
The resistor is identified by a colour code. Most common is the 4 band resistor, band values are as follows - Black- 0, Brown - 1, Red - 2, Orange - 3, Yellow - 4, Green - 5 , Blue - 6, Violet - 7, Grey -8, White 9. The 4 th band is the multiplier.If the picture above is headed "Chicago7" then check the colour bands, they are Blue, 6 green 5 , orange 3, indicating a 65 K ohm resistor.
