IntroductionA resistor is a passive two-terminal electrical component. After it is connected to the circuit, the resistance is fixed, which can limit the current through the branch connected to it. On one hand, the resistance that cannot be changed is called a fixed resistor, on the other hand, the resistances of potentiometers or variable resistors are changeable. The main physical characteristic of a resistor is to transform electrical energy into thermal energy. It can also be said that it is ...

Ⅰ Introduction1.1 What is RAM?Random access memory (RAM) is a type of hardware that stores temporary data for applications on computers, smartphones, gaming consoles, and other devices. To boot up, operating systems (such as Windows and Mac OS) require a particular amount of memory.1.2 What does RAM do?RAM can be thought of as the short-term memory of your computer. It provides temporary storage space for data and program codes currently being used by your computer. Memory is used by your c ...
IntroductionThe Temperature Sensor, a measuring instrument, uses various physical properties of a substance to convert the thermal quantity into the physical quantity, including expansion, resistance, capacitance, electromotive force, magnetic properties, frequency, optical characteristics and thermal noise. Many materials and components change with temperature, so there are quite a few materials that can be used as temperature sensors. Temperature Sensors ExplainedCatalogIntroductionⅠ Temper ...
IntroductionA Capacitor is a component that can store and release electricity, and it is also one of the most commonly used electronic components. Its distinguishing feature is the "Pass Alternating Current (AC), Stop Direct Current(DC)". In a DC circuit, a capacitor is equivalent to an open circuit. Based on this, we will have this question: What the differences betwen ac and dc capacitors? or Are ac and dc capacitors interchangeable? What's the difference between batteries and capacitors? or W ...
Ⅰ IntroductionA battery is an electric power source made up of one or more electrochemical cells with external connections that can be used to power electrical equipment like flashlights, cell phones, and electric cars. The positive terminal of a battery is the cathode, and the negative terminal is the anode when it is supplying electric power. The negative terminal is the source of electrons that will flow to the positive terminal via an external electric circuit. A redox reaction occurs when a ...
Introduction As a passive device, Capacitors have unique functions in electronic circuits such as tuning, bypassing, coupling, and filtering. For example, it is used in the tuning circuit of the transistor radio, and also used in the coupling circuit and bypass circuit of the color TV. With the rapid development of electronic information technology, the update speed of digital electronic products is getting faster and faster. Capacitors play an important role in consumer electronic products suc ...
