The two terminal of a diode are the anode and cathode
Diode
Electronic Component A diode allow electricity to flow in one direction and block it from following the opposite way. Diode primary role is to route electricity from taking an unwanted path within the circuit.
Light emitting diode (LED)
Electronic Component Light emitting diode is like a standard diode in the fact that electrical current only flow in one direction. The main difference is on LED will EMIT light when electricity flow through it. Inside an LED there is an anode and cathode current always flow from the anode (+) to the cathode (-) and never is the opposite direction. The longer leave of the LED is the positive anode outside.

The schematic symbol of NPN and PNP transistor have extremely similar the main difference is the park of the arrow over the emitter terminal. In an NPN transistor then Arrow symbol point out word where in a PNP transistor the arrow sambha point in word.
The PNP transistor symbol is show in the above figure where the arrow mark show. That the flow of current will be form emitter terminal to collector where us in an NPN transistor, the flow of current will be form collector to ammeter terminal.

Electronic components are basic elements used in electronic circuits to perform specific functions. They are essential building blocks for various electronic devices and systems. Here are some common electronic components:
Resistors: Resistors are passive components that impede the flow of electric current. They are used to control current levels, voltage division, and to limit current in specific parts of a circuit.
Capacitors: Capacitors store and release electrical energy. They are made up of two conductive plates separated by a dielectric material. Capacitors are used in timing circuits, filtering, energy storage, and coupling applications.
Inductors: Inductors are passive components that store energy in a magnetic field when current flows through them. They are used in applications such as filtering, energy storage, and signal processing.
Diodes: Diodes allow current to flow in one direction while blocking it in the opposite direction. They are used in rectification, voltage regulation, and signal demodulation.
Transistors: Transistors are active components that amplify or switch electronic signals and control the flow of current. They are crucial in various applications, including amplifiers, oscillators, and digital logic circuits.
Integrated circuits (ICs): Integrated circuits are miniaturized electronic circuits that contain multiple electronic components, such as transistors, resistors, and capacitors, fabricated on a single chip. They are used in almost all electronic devices, including computers, smartphones, and televisions.
Microcontrollers: Microcontrollers are specialized integrated circuits that include a processor core, memory, and input/output peripherals. They are used to control and monitor various electronic systems, such as home automation, robotics, and industrial control systems.
Sensors: Sensors detect and respond to physical phenomena such as light, temperature, pressure, motion, and more. They are used to measure and monitor environmental conditions and provide input to electronic systems.
Relays: Relays are electromechanical devices that control the flow of current by using an electromagnetic coil to switch a set of contacts. They are commonly used to control high-power or high-voltage circuits using low-power signals.
Transformers: Transformers are used to transfer electrical energy between different voltage levels by electromagnetic induction. They are widely used in power distribution systems to step-up or step-down voltages.
These are just a few examples of electronic components, and there are many more with specific functions and applications. The selection and combination of these components depend on the desired functionality of the electronic circuit or device.
