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.

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.

Resistors are circuit elements that impart electrical resistance. The third, blue band, is the multiplier.

This calculator assumes the conductor is round. The resistance of the resistor is determined by the colors of the bands. Capacitor Code - Calculator. Surface mounted resistors SMD use another coding system that uses alphanumeric codes printed on its surface instead of color codes. This is a very good application,it has improved my skill in amplifier engineering when it comes to circult diagram interplitation Thank you. The reading direction is not always clear. The fourth band represents the tolerance in percentage of the resistance value. More commonly, there are five-band resistors that are more precise due to a third significant figure band. 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. In a six-band resistor, the first five bands have the same representation as a five-band resistor followed by one extra sixth band that represents the temperature coefficient of resistance TCR. The resistor color code shown in the table below involves various colors that represent significant figures, multiplier, tolerance, reliability, and temperature coefficient. The third, blue band, is the multiplier. In a four-band resistor, which is the most common, the first two bands also represent the first two significant digits. It will also calculate the minimum and maximum values based on the tolerance ratio.

On the most precise of resistors, a 6 th band may be present. To distinguish the reading direction, the tolerance band width is sometimes printed with 1. Only resistors are addressed by this calculator. Capacitor Code - Calculator.

Resistors are circuit elements that impart electrical resistance. In a four-band resistor, which is the most common, the first two bands also represent the first two significant digits. Temperature Coefficient Color:. Which of these the color refers to is dependent on the position of the color band on the resistor. This is a percentage by which the resistor value can vary. It will also calculate the minimum and maximum values based on the tolerance ratio. Home Language English. The second band represents the second digit of the resistance value. The third band represents the multiplication factor of the resistance value.
