Abstract
A variable resistor includes a resistor element having a first end and a second end, a slider sliding on the resistor element, an adjustable resistor portion having a first end connected to the first end of the resistor element and having a second end, a first terminal connected to the second end of the adjustable resistor portion, a second terminal electrically coupled to the second end of the resistor element, and a third terminal connected to the slider. The adjustable resistor portion is positioned outside of the sliding range of the slider. This variable resistor outputs a precise resistance having s small variation from a predetermined resistance.
