The main material of resistors, carbon. The resistor is the simplest passive element used in electronics. Use it to decrease the value of the current in the circuit to project objectives, taking into account the work of the created device. A resistor is an element with a linear characteristic which follows from the rules stored in the Ohm's law. The effect of the resistor, from physical relies on the capture of the received energy and release it as heat.
How to determine the value of the resistor?
The main differences between opornikami the values of their resistance and method of installation. The second of these properties can be easily recognized, while observing the generic conclusions (SMD or THT). The resistance value, you can also a simple way to determine a resistors przewlekane have special markers, 4 colored stripes. With the help of them, you can easily determine the resistance of the element. The last panel, usually silver or gold and means the permissible level (10% or 5%). The first color of the line indicates the number of tens and the second number of units, and the third is the multiplier number obtained from the two preceding paragraphs. In order to know what is the meaning of certain colors, it is sufficient to find in the Internet the appropriate table (black - 0, brown - 1, red - 2; orange, 3; yellow - 4; green - 5; blue - 6, violet - 7 gray - 8 white - 9). For example: the first band is orange (3), second yellow (4), the third is yellow, and the last silver. This means that the resistor has a tolerance of 10%, and the resistance is the product of 34? and 1000, that is, in the end, 34 k?. On the Internet there are also calculators that allow you to enter just in the right places, the color of the strips - after calculating the result, the computer will give the resistance.
What do we offer?
In this range you will find sets of resistors through hole - several hundred or even several thousand different components rezystancjach, after a dozen or several dozen pieces each interval (or all with the same parameters). Due to the sales in such quantities that the price is for one piece even lower. Also available are specially prepared sets of resistors, e.g., resistors for the LEDs (3 most used values for this purpose - to 30 pieces each). The store offers resistors coal in values from 0.1? to 510 k?. The admission of the services of elements is 1% or 5%, and their nominal power is 0.125 W, 0.25 W or 1W.
