# Resistor calculator. Resistor color code calculator

## LED Resistance Calculator

The calculator above will display the value, the tolerance and performs a simple check to verify if the calculated resistance matches one of the EIA standard values. Rn are the resistances of individual resistors Example Question: If 4 resistors are connected in series and their resistances are 4 Ω, 10 Ω, 15 Ω, 22 Ω find the total resistance in the circuit? Google may also transfer this information to third parties where required to do so by law, or where such third parties process the information on Google's behalf. These resistors can be connected either in series or parallel in a circuit.

• To use this voltage divider resistor calculator, a user must enter the value of the input voltage, V IN, the value of resistor R 1, and the output voltage, V OUT, and click the 'Calculate' button.

## Series Resistor Calculator

This is a necessary step especially with five and six banded metal film resistors.

Next
• The resistor has only 3 bands You don't have to enter the 4th band, as 20% resistors don't have a tolerance ring.

If you have a 5-band resistor switch to this type first. The fourth band represents the tolerance.

Next
• With 5% and 10% resistors the procedure is simple: hold the resistor with the silver or gold band to the right and read the resistor from the left to the right.

## Resistor calculator

In a five-band resistor, the first three bands represent the first three significant digits. 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.

## LED Resistance Calculator

With 4 bands the first and second band represent the first and second signficant digit of the ohm value, the 3 band is the decimal multiplier.

Next
• The first two or three bands determine respectively the first two or three digits of the amount of resistance.

## Resistor color code calculator

How can I calculate its value? It will also calculate the minimum and maximum values based on the tolerance ratio. Digi-Key respects your right to privacy.

• How to calculate the equivalent resistance in a series circuit? Resistors manufactured for military use, may include an additional band indicating the failure rate.

## Resistor Color Code Calculator

The result of this output voltage is calculated in unit volts V. Then you need to multiply that value by the multiplier to get the resistance value of the resistor. The first mode allows you to calculate the total resistance equivalent to a group of individual resistors in parallel.

Next
• For very small electronic components a color code instead of printed text is used to indicate the value, rating or and tolerance.

## LED Resistance Calculator

You should always attempt to work out the value, then check your result against a resistor value chart to see if it's listed there.

• What happens, if I start reading from the wrong end? For example, the resistance of a resistor with 1000 Ω and a tolerance of 10% has an actual resistance between 900 and 1100 ohms.
