Resistance colour code calculator

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

Contains ads In-app purchases. Everyone info. The application is an easy-to-use color code calculator for calculating the resistance of a resistor. 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.

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.

Coded components have at least three bands: two significant figure bands and a multiplier, but there are other possible variations.

.

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 total resistance of resistors in parallel is equal to the reciprocal of the sum of the reciprocals of each individual resistor. In the explanation below, a four-band resistor the one specifically shown below will be used. Switching from 4 bands to 5 prompted very loud and obnoxious ads, then I find the thing just goes right back to 4 bands as soon as I select the first color. Calculator with Themes. Developers can show information here about how their app collects and uses your data. Drinking Game - Ride the Bus. 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. Wooks well, definitely helps me learn. Related Ohms Law Calculator. Resistors cases usually have three to six bands that indicate their resistance, tolerance and sometimes their temperature coefficient of resistance TCR. This calculator assumes the conductor is round. The fourth band is not always present, but when it is, represents tolerance. Its resistance is approximately zero and it is used to connect two traces on a printed circuit board PCB. 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.

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

While circuits can be highly complicated, and there are many different ways in which resistors can be arranged in a circuit, resistors in complex circuits can typically be broken down and classified as being connected in series or in parallel. 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. Other possible resistor variations will be described after. The fourth band represents the tolerance. Related Ohms Law Calculator. If a gold or silver band is present, then they must be at the right end since they are never used for significant digits. The fourth band represents the multiplication factor of the resistance value. Switching from 4 bands to 5 prompted very loud and obnoxious ads, then I find the thing just goes right back to 4 bands as soon as I select the first color. Where: L is the length of the conductor A is the cross-sectional area of the conductor C is the conductivity of the material. Use the following to calculate the resistance of a conductor. Drinking Game - Ride the Bus. To calculate the resistance value, you need to group the values of the significant digits bands — i. The total resistance of resistors in series is simply the sum of the resistances of each resistor.
