Question: What Does 2k7 Resistor Mean?

Can I use a higher ohm resistor?

In general, no.

Resistor values are carefully selected by the circuit designer to allow the circuit to work correctly.

While there is some allowable tolerance, it won’t usually be as much as a different value in the series..

What is a 1% resistor?

Accuracy, resistance value is within +/- 1% of what you want 2. More values available, With 1% resistors you have more nominal values to work with. … Most times in a circuit it is the ratio of two resistors that matter, not the absolute values. So, the ratio of 2 1% resistors have a 2% accuracy.

What does a 1k resistor look like?

The number of ohms is coded with a color and appears as a band on the device itself. … So, a 1k Ω resistor has a value of 1,000 ohms and the number we will code is 1,000. There are three steps for coding a 1kΩ resistor.

What is the resistor used for?

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.

How do you tell if a resistor is out of tolerance?

If there is no tolerance band, it means that the resistor has an actual value within plus or minus 20 percent of the rated value….For the first and second colored bands, the values are as follows:Black = 0.Brown = 1.Red = 2.Orange = 3.Yellow = 4.Green = 5.Blue = 6.Violet = 7.More items…•

What color is a 47k resistor?

What does 3k3 resistor mean?

3,300 ohmsResistors are measured in ohms. 330R means 330 ohms, 22R means 22 ohms. 3k3 means 3,300 ohms, 2k2 means 2,200 ohms. You might also see 3.3k and 2.2k, it’s the same thing.

What is the meaning of 4k7 resistor?

Every 1,000,000 Ohms is known as a Megohm (Mega = one million), abbreviated to the capital letter “M”. As a couple of examples; a 4,700 Ohm resistor would be written as either 4.7K or 4K7, and 5,600,000 Ohms would be written as 5.6M or 5M6.

What color is a 2.2 K ohm resistor?

2k2 / 2.2k ohm Resistor Colour CodeValue2.2 kΩ / 2200 ΩType4 Band Colour CodeColour CodeRed, Red, Red, GoldMultiplierRed, 100ToleranceGold Band ±5%

What is resistor value?

Resistors. A resistor is a device that opposes the flow of electrical current. The bigger the value of a resistor the more it opposes the current flow. The value of a resistor is given in ohms and is often referred to as its ‘resistance’.

What is tolerance of a resistor?

The tolerance of a resistor is the maximum difference between its actual value and the required value and is generally expressed as a plus or minus percentage value. For example, a 1kΩ ±20% tolerance resistor may have a maximum and minimum resistive value of: Maximum Resistance Value.

What color is a 100k resistor?

100k / 100k ohm Resistor Colour CodeValue100 kΩType4 Band Colour Code SystemColour CodeBrown, Black, Yellow, GoldMultiplierYellow, 10000ToleranceGold Band ±5%

What is 100k resistor?

Actual value of 100k Ohm resistor is calculated as: 1st band= Brown= 1 (1st digit) 2nd band= Black= 0 (2nd digit) 3rd band= Yellow= 4(multiplier)= 10000. 4th band= Gold= ±5% (tolerance) Therefore, 10×1000000±5% ==> 1000000Ω ==> 100KΩ

What happens if I use the wrong resistor?

Internally, many power resistors are resistance wire wound around a ceramic form, which means they’re basically an air-core inductor. If you are using such a resistor in a current-sensing application in a switch-mode circuit, you will get spurious readings or inaccurate behaviour.
