Calculator resistance resistor ( bars)

Calculator gives the resistance of the resistor based on the introduced color bars.

Depending on the number of strips – 3 bars – the first two are the resistance , and a third multiplier , the tolerance is 20 % – 4 strips – 2 are first resistance , a third multiplier , a fourth tolerance – 5 bars – the first three bars represent the resistivity , the fourth multiplier , the fifth bar, the tolerance – 6 bars – the first three bars represent the resistance , the fourth factor , the fifth tolerance and temperature coefficient of resistance of the sixth
