  • For resistor calculator, enter the colors on the resistor above.
  • The last two bands that are on 4 and 5 colored resistors are MULTIPLIER and TOLERANCE
  • If the resistor is 4 colored, leave the 3rd band and temperature coefficient empty.
  • If the resistor is 5 colored, leave only the temperature coefficient empty.
