Resistance colour code calculator

The following are tools to calculate the ohm value resistance colour code calculator 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. 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.

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. Resistors cases usually have three to six bands that indicate their resistance, tolerance and sometimes their temperature coefficient of resistance TCR. The bands are read from left to right. The reading direction is not always clear. To distinguish the reading direction, the tolerance band width is sometimes printed with 1.

Binary Calculator. Which of these the color refers to is dependent on the position of the color band on the resistor. Fix this.

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. Use the following to calculate the resistance of a conductor. This calculator assumes the conductor is round. Related Ohms Law Calculator. An electronic color code is a code that is used to specify the ratings of certain electrical components, such as the resistance in Ohms of a resistor. Electronic color codes are also used to rate capacitors, inductors, diodes, and other electronic components, but are most typically used for resistors. Only resistors are addressed by this calculator.

Resistance colour code calculator

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.

Which of these the color refers to is dependent on the position of the color band on the resistor. This calculator will help you identify the value, tolerance and temperature coefficient of a color coded resistor by simply selecting the bands colors. Using the table, the multiplier is thus 1,, In a typical four-band resistor, the first and second bands represent significant figures. The second band represents the second digit 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. Is it used in automated PCB assembly where using the same equipment used to mount other resistors is easier than using a separate machine to install a wire jumper. 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. To calculate the resistance value, you need to group the values of the significant digits bands — i. The fourth band is not always present, but when it is, represents tolerance. Home Language English. The third band represents the third digit of the resistance value. The fourth band represents the multiplication factor of the resistance value. The fourth band represents the multiplier. Only resistors are addressed by this 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.

It will also calculate the minimum and maximum values based on the tolerance ratio. Wooks well, definitely helps me learn. Color-coding is also used for capacitors, inductors and diodes. The total resistance of resistors in series is simply the sum of the resistances of each resistor. Resistor A resistor is a component that is used in electrical circuits to limit the current flow. 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 reading direction is not always clear. Coded components have at least three bands: two significant figure bands and a multiplier, but there are other possible variations. The colors are black, brown, red, orange, yellow, green, blue, violet, grey, white, gold, and silver. In a three-band resistor, the first two bands represent the first two significant digits followed by one band for the multiplier.
