A resistor is a passive two-terminal electronic component which reduces the flow of electrons (electric current) through a circuit. An active component is an electronic component that can generate energy for supplying to an electrical circuit, whereas a passive component can only receive energy but cannot amplify or generate energy. Resistors are mainly used for limiting the current flowing through a circuit, reducing the voltage across a component or as a pull-up/pull-down resistor. The electrical resistance of a resistor is measured in Ohms denoted by the symbol Ω. Generally, resistors are available in two types: through-hole and surface-mount. A 1 kΩ resistor in both through-hole and surface-mount types is shown in Figure 1.15.
Electrical Safety

An inductor or a reactor is a passive electrical component that can store energy in a magnetic field created by the electric current passing through it. An inductor’s ability to store magnetic energy is measured by its inductance, in units of henries (H). Typically, an inductor is a conducting wire shaped as a coil, the loops helping to create a strong magnetic field inside the coil owing to Faraday’s law of induction. Inductors are one of the basic electronic components used in electronics where current and voltage change with time, because of the ability of inductors to delay and reshape ACs.

A sensor is an electronic component, module, or subsystem whose purpose is to detect events changing in its environment and send the information to other electronic devices, mostly a computer processor. A sensor detects and responds to some type of input from the physical environment. The output is generally a signal that is converted to a display that is readable by humans at the sensor location or transmitted electronically over a network for reading or further processing. Sensors in smart homes can be classified as follows in the next few sections.
A new Spk -based sample-size tightening sampling system for lot determination
Published in Quality Technology & Quantitative Management, 2023
Generally, electronic components can be classified into two types: active components such as transistors, diodes and ICs, and passive components such as capacitors, resistors and inductors. It is more common to discuss the technical development of active components; however, advancements in passive components are crucial to certain industries as well. The capacitor is a major component for the storage of electricity in the form of an electric field for coupling and coordination, the resistor is mainly used to adjust the current and voltage, and the inductor stabilizes the electric current, filters the noise of current and prevents interference of electromagnetic waves. Among these three primary passive components, the one with the largest scale of demand in the market is the capacitor, which can be divided according to the materials into ceramic capacitors, aluminum capacitors and tantalum capacitors. To illustrate the applicability of the proposed sampling system, a well-known and widely used capacitor, the Multi-layer Ceramic Capacitor (MLCC) (see, Figures 5 and Figure 6 for a schematic diagram and basic structure) is investigated.

In semiconductor manufacturing processes, thousands of integrated circuits (ICs) are fabricated into a single semiconductor wafer (Liu et al. 2019). Each IC is defined as a set of electronic components, such as transistors, resistors, and capacitors, which are integrated to accomplish a specific function in the electronic devices (Jeong, Kim, and Jeong 2008; Liu et al. 2019). Different wafer faults commonly appear during semiconductor manufacturing. For instance, ridge faults emerge on the topography of wafer surfaces due to uneven temperatures or chemical aging, while material handling and shipping can cause scratches on the topography of wafer surfaces (Jeong, Kim, and Jeong 2008). These faults are key indicators to understand and analyze process variations and failures. Figure 8 shows real examples of the surface topography of non-smooth and smooth copper wafers obtained by a laser interferometer (Rao et al. 2015a). It is observed that the non-smooth copper wafer is associated with different faults such as pits, ridges, and scratches.

By introducing the applications of sensor into the socket, it will only be switched on whenever a certain gesture or condition is detected. A sensor is an electronic components that detect any changes or differences in a particular environment and send the related information to other electronic devices, usually a computer processor. The sensor is often used together with other electronic devices to perform an operation whether as simple as a light or as complex as a computer. In today’s lighting technology, the use of sensor in the lighting system is very common as this helps in saving the cost of operating the system, increasing the efficiency of the system and providing automatic control. The types of sensor that will be focusing in this part are motion detector sensor and light sensor.
