wila lichttechnik electrical components consist of two conductors placed close to each other with a non-conductive insulating medium sandwiched between them, forming a capacitor. When voltage is applied across the two plates of a capacitor, it stores electric charge. The capacitance value is numerically equal to the ratio of the charge on one conductive plate to the voltage between the two plates. The basic unit of capacitance is the Farad (F). In circuit diagrams, capacitive components are usually denoted by the letter C; capacitors are components that store electric charge and electrical energy (electric potential energy). A system of conductors where one conductor is surrounded by another, or where all electric field lines originating from one conductor terminate on another conductor, is called a capacitor.

1. Wiring harnesses are designed to facilitate installation and maintenance, ensuring that electrical equipment can operate under the harshest conditions. Wires of different specifications and colors used by various electrical devices in the vehicle are reasonably arranged and combined into a single unit, bundled with insulating material. This makes the assembly both complete and reliable. 2. Normal selection of wire cross-sectional area and color codes: (1) Correct selection of wire cross-sectional area: Electrical equipment in the vehicle selects the wire cross-sectional area based on the magnitude of the load current. For electrical equipment operating for long durations, wires with 60% of the actual current-carrying capacity may be selected; for electrical equipment operating for short durations, wires with 60%-103% of the actual current-carrying capacity may be used. (2) Selection of wire color codes: To facilitate identification and maintenance, wires in the harness use different colors. For easy labeling in circuit diagrams, wire colors are represented by letters, with the corresponding colors annotated in each circuit diagram.

Inductors generally consist of a bobbin, winding, shielding cover, encapsulation material, magnetic core, or iron core. 1, Bobbin: The bobbin refers to the support for winding the coil. Most large-sized fixed inductors or adjustable inductors (such as oscillator coils, choke coils, etc.) involve winding enameled wire (or silk-covered wire) around the bobbin and then inserting a magnetic core, copper core, or iron core into the inner cavity of the bobbin to increase inductance. Bobbins are typically made of plastic, bakelite, or ceramic and can be shaped according to actual needs. Small inductors (such as color-coded inductors) generally do not use bobbins but instead wind enameled wire directly onto the magnetic core. Air-core inductors (also known as formless coils or air coils, mostly used in high-frequency circuits) do not use magnetic cores, bobbins, or shielding covers; instead, they are wound on a mold which is then removed, leaving a certain distance between the coil turns. 2, Winding: The winding refers to a set of coils with specified functions and is the basic component of an inductor. Windings are classified into single-layer and multi-layer types. Single-layer windings come in two forms: close-wound (where wire turns are adjacent to each other during winding) and spaced-wound (where a certain distance is maintained between each turn during winding); multi-layer windings include layered flat winding, random winding, honeycomb winding, and other methods. 3, Magnetic Core and Magnetic Rod: Magnetic cores and rods are generally made of materials such as nickel-zinc ferrite or manganese-zinc ferrite. They come in various shapes such as "I" shape, cylindrical, cap-shaped, "E" shape, and pot core shape. 4, Iron Core: Iron core materials mainly include silicon steel sheets and permalloy, mostly in "E" shape. 5, Shielding Cover: To prevent the magnetic field generated by some inductors during operation from affecting other circuits and components, a metal shielding cover is added (e.g., oscillator coils in semiconductor radios). Using a shielding cover increases coil loss and reduces the Q value. 8, Encapsulation Material: Some inductors (such as color-coded inductors and color-ring inductors) are sealed with encapsulation material after winding to protect the coil and magnetic core. Encapsulation materials include plastic or epoxy resin.

1. A rotary thermometer is made of a coiled bimetallic strip. One end of the bimetallic strip is fixed, and the other end is connected to a pointer. Due to different degrees of expansion, the two metal strips cause different degrees of curling in the bimetallic strip at different temperatures, causing the pointer to point to different positions on the dial. The temperature can be determined from the reading on the dial. 2. The resistance change of a semiconductor thermometer differs from that of metals; as temperature increases, its resistance decreases, and the magnitude of change is relatively large. Therefore, even small temperature changes can cause significant changes in resistance, resulting in thermometers with high precision, often referred to as thermal sensors. 3. A thermocouple thermometer consists of two different metals connected to a sensitive voltmeter. At different temperatures, the metal junctions produce different potential differences across the ends of the metals. Since the potential difference is very small, a sensitive voltmeter is required for measurement. The temperature can be determined from the voltmeter reading. 4. Optical pyrometer: When an object's temperature is high enough to emit a large amount of visible light, its temperature can be determined by measuring the intensity of its thermal radiation; this type of thermometer is called an optical pyrometer. This thermometer mainly consists of a telescope equipped with a red filter and a circuit containing a small bulb, a galvanometer, and a variable resistor. Before use, establish the relationship between the filament brightness corresponding to different temperatures and the readings on the galvanometer. During use, align the telescope with the object being measured, adjust the resistor until the bulb's brightness matches that of the object, and then read the object's temperature from the galvanometer. 5. Liquid crystal thermometers made with different formulations have different phase transition temperatures. When they undergo phase transitions, their optical properties change, causing the liquid crystal to appear to change color. If liquid crystals with different phase transition temperatures are coated on a piece of paper, the temperature can be determined by the color changes of the liquid crystal. The advantage of this thermometer is easy readability, while the disadvantage is insufficient accuracy. It is commonly used in ornamental fish tanks to indicate water temperature. 11. A digital thermometer uses a temperature sensor to convert (temperature) into a digital signal, which is then displayed in numerical form via a display (such as LCD, seven-segment display, LED matrix, etc.). It can quickly and accurately measure the maximum human body temperature. Compared with traditional mercury thermometers, it offers advantages such as convenient digital reading, short measurement time, high measurement accuracy, memory function, and audible alerts. In particular, digital thermometers do not contain mercury, making them harmless to humans and the surrounding environment, and thus especially suitable for use in hospitals and homes.
