- Current (I): The flow of electric charge, measured in amperes (A).
- Resistance (R): The opposition to current flow, measured in ohms (Ω).
- Capacitance (C): The ability of a component to store charge, measured in farads (F).
- Inductance (L): The property of a circuit that opposes changes in current, measured in henries (H).
Important definitions include:
- Ohm’s Law: A fundamental principle stating that V = I x R, relating voltage, current, and resistance.
- Kirchhoff’s Laws: Two rules that describe the conservation of charge and energy in electrical circuits.
- Operational Amplifier (Op-Amp): A high-gain voltage amplifier with differential inputs, widely used in signal processing.
Understanding these concepts allows engineers to design and analyze complex circuits, making analog electronics essential in many fields, including telecommunications and audio engineering.
