Understanding Electronic Components

Electronic components are basic discrete devices or physical entities in an electronic system that affect electrons or their associated fields. They are either passive (requiring no power to function) or active (requiring power to operate).

Types of Electronic Components

1. Passive Components

• Resistors: Control or restrict the flow of electrical current within a circuit..
• Capacitors: Temporarily hold electrical energy and discharge it as required.
• Inductors: Retain energy in a magnetic field created by the flow of electrical current.

2. Active Components

• Transistors: Function as switches or amplifiers in electronic circuits.
• Diodes: Permit current to flow in one direction and block it in the opposite direction.
• Integrated Circuits (ICs): Miniature circuits containing transistors, resistors, and capacitors, used in various electronic devices.

3. Electromechanical Components

• Switches: Control the current flow by either completing or interrupting a circuit.
• Relays: Electrically operated switches which are used to control a circuit.
