Resistance colour code calculator

The following are tools to calculate the ohm value and tolerance based on resistor color codes, resistance colour code calculator total resistance of a group of resistors in parallel or in series, and the resistance of a conductor based on size and conductivity. Use the following to calculate the resistance of a conductor.

The application supports color codes for 3, 4, 5, and 6-band resistors. Resistor A resistor is a component that is used in electrical circuits to limit the current flow. When a current I of one Ampere passes through a resistor with a voltage drop U of one Volt, the resistance of a resistor R corresponds with one Ohm. Resistors come in variation with 3, 4, 5, or 6 colors bands.

Resistance colour code calculator

This calculator will help you identify the value, tolerance and temperature coefficient of a color coded resistor by simply selecting the bands colors. It will also calculate the minimum and maximum values based on the tolerance ratio. This calculator supports resistors with 3, 4, 5, and 6 bands. Color-coding is a method used to indicate the resistive value, tolerance, and temperature coefficient of resistors with low wattage rating because of their small size. Color bands are used because they can be easily and cheaply printed on a small electronic component. Color-coding is also used for capacitors, inductors and diodes. When the resistor body surface is large enough, as in large wattage resistors, the resistance value, tolerance, and wattage are usually printed on the body of the resistor. Surface mounted resistors SMD use another coding system that uses alphanumeric codes printed on its surface instead of color codes. The coding is defined in the international standard IEC It describes the coding standard for both resistors and capacitors.

A larger gap between the tolerance band and the other bands is sometimes noticeable.

With this resistor color code calculator, you'll quickly and easily find out the resistance of your resistor component. Just choose how many bands your resistor has — 4, 5, or 6, select the colors , and in the blink of an eye, you'll get the resistance with tolerance, range, and temperature coefficient value if you've chosen 6 band resistor color code. If you want to understand how to read resistor color code, scroll down, and you'll find their formulas and explanation. Also, we show a 10k resistor color code as well as many other informative examples. Color bands are an easy and cheap way of indicating the value of an electronic component. The printed alphanumeric codes would be too small to read on the tiniest resistors, so the color code was developed in the early s. The first question which usually arises is: how do I know from which end I should start reading my resistor color code? Fortunately, a couple of visual hints exist! In a usual case, the bands are not spaced regularly — there's a gap, and bands are somehow grouped.

Everyone info. This calculator assumes the conductor is round. The sixth band represents the temperature coefficient of the resistance value. When the resistor body surface is large enough, as in large wattage resistors, the resistance value, tolerance, and wattage are usually printed on the body of the resistor. To calculate the resistance value, you need to group the values of the significant digits bands — i. It describes the coding standard for both resistors and capacitors. Its resistance is approximately zero and it is used to connect two traces on a printed circuit board PCB. For this example, refer to the figure above with a green, red, blue, and gold band. Tolerance is the percentage of error between the actual measured resistive value and the stated value. Resistor Color Code Calculator. Contains ads In-app purchases.

This is a very good application,it has improved my skill in amplifier engineering when it comes to circult diagram interplitation Thank you. This is due to the manufacturing process and it is expressed as a percentage of its preferred value. It will also calculate the minimum and maximum values based on the tolerance ratio. Tolerance is the percentage of error between the actual measured resistive value and the stated value. Contains ads In-app purchases. In a three-band resistor, the first two bands represent the first two significant digits followed by one band for the multiplier. In the explanation below, a four-band resistor the one specifically shown below will be used. Financial Fitness and Health Math Other. It describes the coding standard for both resistors and capacitors. To calculate the resistance value, you need to group the values of the significant digits bands — i.
