An electronic component is any basic discrete device or physical entity in an electronic system used to affect electrons or their associated fields. Electronic components have a number of electrical terminals or leads. Components can be classified as passive, active, or electromechanic. However, electronic engineers who perform circuit analysis use a more restrictive definition of passivity.
Passive components can’t introduce net energy into the circuit. Passive components include two-terminal components such as resistors, capacitors, inductors, and transformers. Most passive components with more than two terminals can be described in terms of two-port parameters that satisfy the principle of reciprocity—though there are rare exceptions. Conduct electricity easily in one direction, among more specific behaviors. A diode whose AC capacitance varies according to the DC voltage applied. Transistors were considered the invention of the twentieth century that changed electronic circuits forever.
Reader can contain thousands of e — but I believe that most technical people are inherently honest and I trust them to pay what they think is appropriate.

A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. Components incapable of controlling current by means of another electrical signal are called passive devices. Resistors, capacitors, inductors, and transformers are all considered passive devices. Capacitors store and release electrical charge.
They are used for filtering power supply lines, tuning resonant circuits, and for blocking DC voltages while passing AC signals, among numerous other uses. Electrical components that pass charge in proportion to magnetism or magnetic flux, and have the ability to retain a previous resistive state, hence the name of Memory plus Resistor. LC circuit, used in tunable transformers and RFI filters. Transducers generate physical effects when driven by an electrical signal, or vice versa. Only the most common ones are listed here. Components that use the effect as mechanical transducers. On a circuit diagram, electronic devices are represented by conventional symbols.
