Description
Technical field
The utility model relates to field of electrical components, relates in particular to a kind of electronic potentiometer.
Background technology
The scalar potential of electrostatic field is called electromotive force, or is called electrostatic potential. In electric field, certain point chargeEnergy of position with it with the quantity of electric charge (with positive and negative relevant, when calculating by energy of position and electric chargePositive and negative all bringing into can judge this electromotive force size and positive and negative) ratio, be called the electricity of this pointGesture (also can claim current potential), uses conventionallyRepresent. Electromotive force is to describe electricity from energy point of viewThe physical quantity of field. (electric-field intensity is to describe electric field from the angle of power). Electrical potential difference can closed(in the time that electrical potential difference is quite large, the insulators such as air also can become and lead to close generation current in circuitBody). Electromotive force is also referred to as current potential. Potentiometer be there are three exits, resistance can be by certainPlant the resistive element that Changing Pattern regulates. Potentiometer is conventionally by resistive element and brush movablyComposition. In the time that brush moves along resistive element, obtain and become certain pass with displacement at outputResistance value or the voltage of system. Potentiometer both can have been done three-terminal element use also can be made as two-terminal elementWith. The latter can regard a variable resistance as, because its effect in circuit is to obtain with defeatedEnter voltage (applied voltage) and become certain relation to obtain output voltage, be therefore referred to as potentiometer.Brush, in mobile process, and certainly exists friction between resistive element and peripheral components, longThe friction of time easily damages potentiometer, reduces its service life, and potentiometer is regulatingAfter putting in place, often cannot be fixed on a certain gear, in use procedure, be prone to maloperation.
