Usually, 4 band resistors are the most common type of resistors. You can also find 3band, 5 bands, and 6 band resistors.
4 Band Resistor – The first two bands denote the first two digits of the resistance value and the third band is the multiplier, which is the number of zeros to be added or the decimal points to be shifted. The fourth band represents tolerance, which is the percentage of error or deviation in the resistance value. The actual value of the resistor can be more or less in the percentage of tolerance value from the nominal value.
3 Band Resistor – In 3 band resistors similar to a four-band the first two bands denote the first two digits and a multiplier third band. The only difference is the absence of the tolerance band, its default tolerance value is ±20%.
5 Band Resistor – A 5-band resistor has an additional third significant digit. So first 3 bands as first 3 digits, then fourth multiplier and fifth tolerance band.
6 Band Resistor – Similar to 5 band resistors it also has a third significant digit and a 6th band for indicating the temperature coefficient of resistor.
