Resistor color code calculator

Calculating Resistor Colour Code Values For example, a resistor has the following coloured markings; Yellow Violet Red = 4 7 2 = 4 7 x 102 = 4700Ω or 4k7 Ohm. The fourth and fifth bands are used to determine the percentage tolerance of the resistor.

How do you calculate resistors?

If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.

What is resistor color coding chart?

Components and wires are coded with colors to identify their value and function. Resistor Color Coding uses colored bands to quickly identify a resistors resistive value and its percentage of tolerance with the physical size of the resistor indicating its wattage rating.

What color is a 470 ohm resistor?

470 Ohm 0.5W High Quality Carbon Film Resistor (CFR) with ±5% Tolerance and Tin Plated Copper Leads. 470 Ohm Resistor Color Code: Yellow, Violet, Brown, Golden.

What color is a 2.2 K ohm resistor?

What is 2.2k ohm Resistor color code for 4-band? The color code of 2.2 k resistor is Red-Red-Red-Gold. From the above resistor color code table, you will find that Red stands for 2 and Red for 2. The third band is Red, so it means a multiplier value of 2 (100).

What is the color code for a 220 ohm resistor?

Hence the colour code of 220 ohm resistor will be – red, red and brown.

What color is a 10K ohm resistor?

A 10K Ohm resistor can be identified via resistor color codes of Brown-Black-Orange-Gold or Brown-Black-Black-Red-Gold.

What is the most common resistor?

Carbon Resistors are the most common type of Composition Resistors. Carbon resistors are a cheap general purpose resistor used in electrical and electronic circuits.

Which is best resistor?

Foil resistors are considered to have the best TCRs and precision of any resistor commonly available today. These low-noise components also have very low capacitance and no inductance at all.

What are the two most common resistors?

Basic distinction of resistor types

Fixed resistors: Fixed resistors are by far the most widely used type of resistor.
Variable resistors: These resistors consist of a fixed resistor element and a slider which taps onto the main resistor element.

How do you read a color code?

Hex color codes start with a pound sign or hashtag (#) and are followed by six letters and/or numbers. The first two letters/numbers refer to red, the next two refer to green, and the last two refer to blue. ... For example:

A=10.
B=11.
C=12.
D=13.
E=14.
F=15.

How do you read a 5 color resistor?

If the colors on a 5 band resistor is in this order: brown, green, red, blue and violet (as shown in figure). The values of color bands will be like this: Brown = 1, Green = 5, Red = 2, blue = 106, Violet = 0.10%.
