A contrivance for adjusting or regulating the strength of electrical currents, operating usually by the intercalation of resistance which can be varied at will.
resistor for regulating current
an adjustable electrical switch that can be tested and, as necessary, replaced
an variable resistor that has only two terminals
a variable controller that directs the amount of current flowing to many smaller appliance components
a variable reisstor with two terminals, one fixed and one sliding
An electrical appliance used to raise or lower the resistance of a circuit and correspondingly to decrease or increase the current flowing.
An instrument for regulating electric current.
variable resistor used for the purpose of adjusting the current in a circuit.
A device for regulating strength of an electric current by varying the resistance. Also called a dimmer.
Two terminal variable resistor used to control current.
