Abstract

A variable resistor is characterized by mainly comprising a containing cavity, at least two electrodes, resistance liquid, and a floating conductor. A variable resistor is characterized by mainly comprising a containing cavity, at least two electrodes, resistance liquid, a floating conductor, and an easily deformable wire. A variable resistor cluster is formed by arraying the variable resistors. A variable resistor cluster is formed by coaxially connecting the variable resistors in series. A motor starter is formed by reasonably connecting the variable resistors or the variable resistor clusters with a motor according to needs. The variable resistors, the variable resistor clusters and the motor starter have the advantages of simple structure, long service life and low cost.
