How many K is the resistance of brown, black, red, silver?

Brown, black, red, silver is 10 * 10 2 = 1000 ohms, that is, 1k color ring resistance reading:

The color ring resistance is divided into four color rings and five color rings, let's talk about the four color rings first. As the name suggests, four colored rings are used to represent the magnitude of the resistance. Each color represents a different number, as follows:

Brown 1 Red 2 Orange 3 Yellow 4 Green 5 Blue 6 Purple 7 Gray 8 White 9 Black 0 Gold and silver indicate errors.

The meaning of each color ring is as follows:

The first color wheel: the first digit of the resistance value;

The second color ring: the second digit of the resistance value;

The third color wheel: power of 10;

The fourth color wheel: error representation.

For example: resistance color wheel: brown, green, red gold, first place: 1; 2nd place: 5; Third place: 10 to a power of 2 (i.e. 100); The error is 5%; That is, the resistance value is: 15 100 = 1500 ohms = thousand ohms =

And precision.

The higher "five-color ring" resistor, with five color rings to indicate the resistance value of the resistor, is as follows:

The first color wheel: the first digit of the resistance value;

The second color ring: the second digit of the resistance value;

The third color wheel: the third digit of the resistance value;

The fourth color ring: the power of 10 of the resistance multiplier;

The fifth color wheel: error (commonly brown, 1% error).

The first two rings of the four-ring resistor are valid values, and the third ring represents the number of zeros, so the resistance should be: 1000 ohms or 1k

Hello, dear, I am glad to answer for you: how much resistance is brown, black, silver and gold? A:

Hello dear: The resistance of ohms is expressed by four rings: 1. Brown, black, silver, gold, and 5%; Or 2, brown black silver silver euro 10%, color ring resistance is divided into four rings and five rings, usually with four rings.

The penultimate ring can be gold (for and silver (for , and the last ring can be colorless (20%). The five-ring resistance is a precision resistance, the first three rings are numerical values, and the last ring is an error color ring, usually gold, silver and brown three colors, the error of gold is 5%, the error of silver is 10%, the error of brown is 1%, the error of colorless is 20%, and there are occasionally green ghostwriting errors, green errors are. Precision resistors are commonly used in military, aerospace, etc.

Brown, red, green, silver 12*10 5 = 1200000 ohms = 1200k (thousand ohms) = megaohms), error 10% gray-red, black-silver-brown 820*10 (-2) = ohms, error 1%.

Red (2), Yellow (4), Brown (1), Silver (10%)

Resistance = 24 10 = 240 ohms.

Error: 10% (i.e. 12 ohms).

Red, yellow, and brown represent hundreds, tens, and singles, respectively!

That's 240

And silver represents an error of 10%!

Answer: Resistance, error of 10%.

The answer is absolutely accurate, and this knowledge is explained in detail in Elective 3-3 of the High School Physics Book Teaching Edition.

The first and second rings represent the first two digits of the resistance respectively; The third ring represents the magnification; The fourth ring represents the error. The key to rapid identification is to determine the resistance value within a certain order of magnitude according to the color of the third ring, such as how many ks or tens of k, and then read the number of the first two rings"generations"Go in and read out the numbers quickly.

Here are a few key points to master this method:

1) Memorize the first.

The number represented by each color of the first and second rings. You can remember it like this: Brown 1, Red 2, Orange 3, Yellow 4, Green 5, Blue 6, Purple 7, Gray 8, White 9, Black 0Read them together and repeat them several times to memorize them.

Keeping in mind the range of resistance represented by the color of the third ring is the key to quick understanding. Specifically:

Golden: What time is it?

Black: Dozens

Brown: hundreds, dozens

Red: What time is it

Orange: a few dozen k

Yellow: hundreds, tens of ks

Green: what time is it

Blue: a few dozen m

From the point of view of order of magnitude, they can be divided into three large grades in vivo, namely: gold, black, and brown are ohmic; Red orange', yellow is in the thousand-ohm range; Green and blue are in the megaohm range. This is to make it easier to remember.

3) When the second ring is black, the color of the third ring represents an integer, i.e. several, dozens, hundreds of k, etc., which is a special case when reading, pay attention to. For example, if the third ring is red, then its resistance is a whole number of k.

4) Remember the error represented by the color of the fourth ring, i.e.: 5 for gold; 10 for silver; Colorless is 20

You can use the ohm file of the multimeter, combine and judge it yourself according to the following figure, you can't be color blind, color blindness can find someone to help.

Gold, silver, black, and brown resistors are common resistors in electronic components, and are usually used in circuits such as current limiting, voltage division, and filtering. The size of the resistor to buy depends on the specific application scenario of Tongluo.

In general, there are two main parameters to consider when choosing a resistor size: resistance value and power. The resistance value refers to the magnitude of the resistance of the resistor, usually in ohms ( ). Power refers to the maximum power that a resistor can withstand when the energy consumption is too large, usually measured in watts (W).

The first step is to determine the desired resistance value. If you are studying or experimenting, it is recommended to buy some commonly used resistor values, such as k, etc., or you can choose to buy a round of Bibrillation with multiple resistors of different sizes, which will improve your flexibility.

Secondly, it is necessary to select the appropriate power according to the required resistance value. It is best to have a slightly larger power than the power required for the resistors in the circuit to ensure stability and reliability. Generally speaking, the common power is 1 8W, 1 4W, 1 2W, 1W, 2W, etc.

Finally, you need to choose the quality and brand of the resistor. There are many manufacturers on the market that produce resistors, and it is recommended to choose well-known brands or manufacturers with a good reputation to ensure the quality and performance of the resistors and avoid other failures caused by resistor quality problems.

In short, the size of the gold, silver, black, and brown resistors should be determined according to the specific needs. Choosing the right resistance, power and quality will bring you a better experience.
