Electronics is the branch of physics and engineering concerned with the design and study of electronic circuits which use active electrical components to control or modify electric signals.

Core Concepts

  • Electric Charge: The fundamental property of matter that causes it to experience a force when placed in an electromagnetic field.
  • Electric Current: The flow of electric charge.
  • Voltage: The electric potential difference between two points.
  • Resistance: The opposition to the flow of electric current.
  • Ohm's Law: Relates voltage, current, and resistance (V = IR).
  • Circuits: Closed paths through which electric current can flow.
  • Electronic Components: Devices used in electronic circuits (resistors, capacitors, inductors, transistors, diodes, etc.).

Key Areas

  • Circuit Analysis: Analyzing the behavior of electronic circuits.
  • Electronic Devices: Understanding the operation of various electronic components.
  • Signals and Systems: Processing and transmitting information using electrical signals.
  • Digital Electronics: Dealing with discrete values (0 and 1) of electrical signals.
  • Analog Electronics: Dealing with continuous signals
