How to calculate resistance colour code calculator?
For calculating the resistance colour code calculator, we need to group the values of the significant digits bands; it means we will take the values of the first two or three bands from the left, depending on the total number of bands, then we will multiply that value by the multiplier to get the resistance value of the resistor.
What is the color code for a resistance resistor?
Resistor Color Code. Band 1 Band 2 Band 3. .22 ohm R22 Red Red Silver .27 ohm R27 Red Purple Silver .33 ohm R33 Orange Orange Silver .39 ohm R39 Orange White Silver .47 ohm R47 Yellow Purple Silver Notation Tolerance.
What do the colours of the resistance bands on a circuit mean?
The band just next to the tolerance band is the multiplier band. So if the colour of this band is Red (representing 2), the value given is 10 2. The tolerance values represent by how much the resistance can vary from its mean value in terms of percentage. A gold band represents the lowest variation, so be sure to buy these at the electronics store.
What to do if the resistance code seems doubtful?
If the resistance code seems doubtful, measure the resistance with the help of an ohmmeter. The first band is always closest to the lead and Gold-silver bands are always located at the last.
