xABBDIVIZEDRIVE electrical component is a resistive component with three terminals, whose resistance can be adjusted according to a specific variation law. A potentiometer typically consists of a resistive element and a movable wiper. When the wiper moves along the resistive element, a resistance value or voltage related to the displacement is obtained at the output terminal. A potentiometer can be used as a three-terminal component or as a two-terminal component. The latter can be regarded as a variable resistor. Since its function in the circuit is to obtain an output voltage that has a certain relationship with the input voltage (applied voltage), it is called a potentiometer. A potentiometer is a type of variable resistor. It usually consists of a resistive element and a rotating or sliding system, i.e., a moving contact moves on the resistive element to obtain a partial voltage output. The function of a potentiometer is to adjust voltage (including DC voltage and signal voltage) and current magnitude. Structural features of a potentiometer: The resistive element of a potentiometer has two fixed terminals. By manually adjusting the shaft or slider, the position of the moving contact on the resistive element is changed, thereby changing the resistance value between the moving contact and any fixed terminal, thus changing the magnitude of voltage and current. A potentiometer is an adjustable electronic component. It consists of a resistive element and a rotating or sliding system. When a voltage is applied across the two fixed contacts of the resistive element, changing the position of the contact on the resistive element via the rotating or sliding system yields a voltage between the moving contact and the fixed contact that is related to the position of the moving contact. It is mostly used as a voltage divider, in which case the potentiometer is a four-terminal component. A potentiometer is basically a sliding rheostat, available in several styles, generally used for volume control in speakers and power adjustment for laser heads. A potentiometer is an adjustable electronic component. It is a variable resistor used for voltage division. On the exposed resistive element, one or two movable metal contacts are pressed firmly. The contact position determines the resistance between either end of the resistive element and the contact. Classified by material: wire-wound, carbon film, and solid-core potentiometers; classified by the relationship between the output-to-input voltage ratio and the rotation angle: linear potentiometers (linear relationship) and functional potentiometers (curvilinear relationship). Main parameters include resistance value, tolerance, and rated power. Widely used in electronic equipment, such as for volume control in audio systems and receivers.

xABBDIVIZEDRIVE electrical component applications

Thermistors can also be used as electronic circuit components for temperature compensation in instrument circuits and cold-junction temperature compensation for thermocouples. Utilizing the self-heating characteristic of NTC thermistors enables automatic gain control, forming RC oscillator amplitude-stabilization circuits, delay circuits, and protection circuits. When the self-heating temperature is much higher than the ambient temperature, the resistance is also related to the heat dissipation conditions of the environment. Therefore, this characteristic of thermistors is often utilized in anemometers, flow meters, gas analyzers, and thermal conductivity analysis to create specialized detection elements. PTC thermistors are mainly used for overheat protection of electrical equipment, contactless relays, constant temperature control, automatic gain control, motor starting, time delay, automatic degaussing in color televisions, fire alarms, and temperature compensation. Main disadvantages: (1) severe nonlinearity in the relationship between resistance and temperature; (2) poor consistency and interchangeability of components; (3) components are prone to aging and have poor stability; (4) except for special high-temperature thermistors, most thermistors are only suitable for the range of 0 to 151 °C, which must be noted during use.

The static characteristics of a sensor refer to the relationship between the output quantity and the input quantity for static input signals. Since the input and output quantities are independent of time in this case, their relationship, i.e., the static characteristics of the sensor, can be described by an algebraic equation without time variables, or by a characteristic curve plotted with the input quantity as the abscissa and the corresponding output quantity as the ordinate. The main parameters characterizing the static characteristics of a sensor include: linearity, sensitivity, hysteresis, repeatability, drift, etc. (1) Linearity: Refers to the degree to which the actual relationship curve between the sensor's output and input deviates from the fitted straight line. It is defined as the ratio of the maximum deviation between the actual characteristic curve and the fitted straight line over the full scale range to the full-scale output value. (2) Sensitivity: Sensitivity is an important indicator of a sensor's static characteristics. It is defined as the ratio of the increment in the output quantity to the corresponding increment in the input quantity that causes this change. S is used to denote sensitivity. (3) Hysteresis: Hysteresis is the phenomenon where the input-output characteristic curves do not coincide when the input quantity changes from small to large (forward stroke) and from large to small (reverse stroke). For the same magnitude of input signal, the output signals for the forward and reverse strokes of the sensor are not equal; this difference is called the hysteresis error. (4) Repeatability: Repeatability refers to the degree of inconsistency in the characteristic curves obtained when the sensor's input quantity undergoes multiple consecutive full-scale changes in the same direction. (5) Drift: Sensor drift refers to the phenomenon where the sensor's output changes over time while the input quantity remains constant. There are two causes of drift: one is the sensor's own structural parameters; the other is the surrounding environment (such as temperature, humidity, etc.). (6) Resolution: When the sensor's input increases slowly from a non-zero value, an observable change in the output occurs after exceeding a certain increment. This input increment is called the sensor's resolution, i.e., the minimum input increment. (7) Threshold: When the sensor's input increases slowly from zero, an observable change in the output occurs after reaching a certain value. This input value is called the sensor's threshold voltage.

The characteristics of an inductor are exactly opposite to those of a capacitor; it has the property of blocking alternating current (AC) while allowing direct current (DC) to pass through smoothly. The resistance when a DC signal passes through the coil is simply the resistance of the wire itself, resulting in a very small voltage drop; when an AC signal passes through the coil, a self-induced electromotive force (EMF) is generated across the coil terminals. The direction of the self-induced EMF is opposite to that of the applied voltage, hindering the passage of AC. Therefore, the characteristic of an inductor is to pass DC and block AC; the higher the frequency, the greater the coil impedance. Inductors often work together with capacitors in circuits to form LC filters, LC oscillators, etc. Additionally, utilizing the properties of inductance, people have manufactured chokes, transformers, relays, and other devices. Passing DC: Refers to the inductor presenting a conductive state to DC. If the resistance of the inductor coil is ignored, DC can pass through the inductor 'unimpeded.' For DC, the coil's own resistance offers very little opposition, so it is often ignored in circuit analysis. Blocking AC: When AC passes through the inductor coil, the inductor offers opposition to the AC. This opposition to AC is the inductive reactance of the coil.
