Electronics is an application form involving electronic science. It contains active components, passive components and other basic technology circuits, making it an important part of engineering.
Active components rely on energy (usually from DC circuits that we choose to ignore) and can usually inject power into the circuit, although this is not part of the definition. Active components include amplifying components such as transistors, triode vacuum tubes (valves) and tunnel diodes.
Passive components cannot introduce net energy into the circuit. They also cannot rely on a power source unless the (AC) circuit to which they are connected is available. As a result, they cannot amplify (increase the power of the signal), although they may increase the voltage or current (for example, through a transformer or resonant circuit). Passive components include two-terminal components, such as resistor, capacitor, inductors and transformers.
Electromechanical components can perform electrical operations through the use of moving parts or through electrical connections.
We live in an electronic age, where robots can do human work more easily and efficiently. Capsules and tablets contain wireless sensors that collect information from the human body for diagnosis. Transparent smartphones will appear in the next few days, we can see them through them, and they may cause windows or mirrors in our homes to be used as PC screens and TV monitors. The world is growing fast, so technology enthusiasts must upgrade as changes occur. Moreover, without electronic products, it may take a few more hours. They have become an important part of our daily work.
