A component of the sliding resistor circuit, the position of the important component of the important component, the position of the mobile slide sheet to change the change, change the resistance resistance resistance resistance resistance resistance resistance resistance resistance resistance changes, come to change A sliding barrier composition includes a terminal, resistance wire resistance, metal rod metal rod and porcelain porcelain cylinder.
First, work principle
One of the resistors, its principle principle can change the resistance by accessing the length of the electrical resistance line resistance line through access to the circuit circuit to change the resistance Large nickel chromium alloy, small metal rods are generally small, so, so, must, must, must, resistance wire, resistance wire, resistance, resistance, resistance wire, resistance wire, resistance wire, resistance, resistance, resistance, resistance, resistance, resistance, resistance, resistance, resistance, resistance, resistance, resistance, resistance, resistance, resistance, resistance, resistance
Second, the main role
(1)) Protection. Essence
2) (2) Character through the circuit part to change the direction direction direction direction direction direction direction direction direction direction direction direction of the circuit in the direction direction direction direction direction direction is connected through the circuit part. Select the resistance wire according to the requirements….
3)) Change changes. Explore Ohm’s Law ((= = = = = = = = =
Third, the main materials
The material material of the sliding resistor is generally gold silk gold silk gold wire. Wind chromium alloy wire winding on the insulation cylinder insulation cylinder of the insulation cylinder, and the distance between the two ends, thereby the metal rod electrical resistance resistance. There are also, such as such as carbon (sliding barrier.
Fourth, the function of electrical appliances
However, in general, there are many shapes such as the potentiometer shape, body shape and other shapes;;;; there are straight sliding and straight -type, rotating rotating type, rotating rotation type, multi -circle and non -contact type, etc. Form; Materials are divided into carbon carbon membranes ,,, synthetic film, electrical conductance, metal -metal glass glass glaze and comparison time, the resistance value changes from the rotation angle. The law of changes and changes is three or three
X -type straight line, its resistance angle. It is used for voltage adjustment current. Essence If you are adjusting, adjustment, adjustment and adjustment
Z -type index type, changes in changes in changes in changes in changes in changes in changes in changes in changes, changes, changes, changes, changes, changes, changes, changes, changes, changes, changes, changes, changes slowly, slow, and then slowly, slow, slow, slow slowly). The most sensitive sensitivity and sensitivity of the volume changes in the process of volume changes in the process of the process of the process of the process of the process of the process is stable. Essence Essence
Type D pair, the change of its rotation change and changes (that is, the change quickly and fast adjust the black and white, which may be appropriate.
The circuit is adjusted, and a low -carbon film is adopted; when accurate adjustment and adjustment,
