Application: potentiometer
Use: Select ,,, tune.Essence
Construction: porcelain tube, sliding metal stick.Essence
Change: Change the length of the circuit in the circuit.Essence
Advantages and disadvantages: The resistance of the circuit can be gradually, but it means the circuit.Essence
Function: ① Through the mid -resistance, the current in the circuit is gradually in the circuit and the two parts of the circuit
Depending on the appropriate barrier; series circuit: "One -one";;; the access circuit shall be controlled.EssenceEssenceEssence
Nameplate: a sliding barrier is marked with the words "50Ω1.5A", and 50Ω indicates that the maximum resistance value of the sliding barrier is 50Ω or the range of the variable resistance is 0 to 50Ω.1.5A indicates that the maximum current allowed to pass the sliding barrier is 1.5A.
: ①: ① The nameplate of the nameplate is connected to the circuit.Essence
