What is the basic principle of electronics?

 The basic principle of electronics is the control and manipulation of the flow of electrons (electric current) to perform useful tasks like amplification, computation, signal processing, and control.

Key Concepts Behind This Principle:

Electric Current:

• Flow of electrons through a conductor (usually a wire).
• Measured in amperes (A).
• Voltage (Potential Difference):
• The "push" that drives electrons through a circuit.
• Measured in volts (V).

Resistance:

• Opposition to current flow.
• Measured in ohms (Ω).

Follows Ohm’s Law:

• (Voltage = Current × Resistance)

Electronic Components:

• Passive: Resistors, capacitors, inductors — don’t require power to function.
• Active: Transistors, diodes, ICs — control the flow of current, often requiring a power source.

Semiconductors:

• Materials like silicon that can act as conductors or insulators depending on conditions.
• Basis for modern electronic devices like transistors, diodes, and integrated circuits.

Circuits:

• Interconnected electronic components forming a pathway for current.
• Can be analog (continuous signals) or digital (discrete signals like 0s and 1s).
