Product Information

But, dropping the "Ω" leaves the problem of how to represent a resistor value when the multiplier is 1. It’s easiest to learn four band resistors first. Once you learn the four band system, it is very easy to understand five and six band resistor color codes. The Four Band 100k Ohm Resistor The final band indicates the tolerance of the resistor. The tolerance explains how much more or less the actual resistance of the resistor can be compared to what its nominal value is. No resistor is made to perfection, and different manufacturing processes will result in better or worse tolerances. For example, a 1kΩ resistor with 5% tolerance could actually be anywhere between 0.95kΩ and 1.05kΩ. All resistors have a tolerance, which means that the value is unlikely to be exactly 100k Ohms. Higher quality resistors have better tolerances. We then multiply that number by the multiplier indicated with the 3 rd band (yellow) which has the value of; x10 4 = 10000.

I wrote a little code in excel, to whatch the effect of changing the value(s) of the resistor(s), which of course had to be within the common E12 range. Band Three – Multiplier: Takes the digits and multiplies them by a value given by this band. The actual multiplier is 10 n, where n is a value that corresponds to the color of the band. In this case, the third band is yellow which corresponds to the number 5. Therefore the multiplier is 10 5 = 10,0000. It is very easy to read 5 or 6 band resistors if you already know how to use four band resistor color coding. 5 Band 100K Resistor Color Code Band One – 1 st Digit: This is the first digit of the resistance value. The first band is brown, which corresponds to a value of 1. In a four-band resistor, which is the most common, the first two bands also represent the first two significant digits. The third band represents the multiplier. The fourth band represents the tolerance.I can devide every value by 10, keeping the balance the same, while having the right pulldown value. The same approach is used with capacitors: 2p2, 22p, 220p, 2n2, 22n, 220n, 2u2, 22u, 220u. In the old days larger values were still marked µF so the next decade was marked 2200u but with large capacitor values common now we're seeing 2m2, 22m, etc. I've never seen an equivalent of the 'R' as in 2C2 for a 2.2 F - yet! 2F2 may be more sensible. The current use of 'R' would then be excused (4R7 instead of 4Ω7) on the basis that Ω isn't readily available on most keyboards.

A 100K resistor is a type of resistor with a value of 100,000 ohms. Resistors are passive electronic components that are used to resist the flow of electrical current in a circuit. They are commonly used to limit the current in a circuit, to divide the voltage in a circuit, to provide a reference voltage, or to create a voltage drop in a circuit. The value of a resistor is expressed in ohms, and it determines the amount of resistance that the resistor offers to the flow of electrical current. The higher the value of the resistor, the more resistance it offers, and the lower the current that will flow through it. In my new concept I integrated the pulldown resistor as beeing part of the left side of the resistors. To calculate the resistance value, you need to group the values of the significant digits bands — i.e., the values of the first two or three bands from the left, depending on the total number of bands. Then you need to multiply that value by the multiplier to get the resistance value of the resistor. Five band resistors have a third significant digit band between the first two bands and the multiplier band. Five band resistors also have a wider range of tolerances available.

Peek inside the guts of a few carbon-film resistors. Resistance values from top to bottom: 27Ω, 330Ω and a 3.3MΩ. Inside the resistor, a carbon film is wrapped around an insulator. More wraps means a higher resistance. Pretty neat! Resistors are electronic components which have a specific, never-changing electrical resistance. The resistor's resistance limits the flow of electrons through a circuit.
