Resistor Calculator Section Two-way conversion Calculate resistor values by selecting its band colours on the grid. You can also get the colour bands of the desired resistor value by typing its value in ohms in the top-right corner. Support 4 bands and 5 bands. Tap on the resistor to switch between 4 and 5 bands. Scanning Section Resistor Types supported Only 4-bands resistors with a clear background colour are supported. Resistor Placement · Make sure only 1 resistor is inside the sq
