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.

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

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.

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.

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.

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.

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.
