Study Notes
Introduction to Electronic Circuits
- Electronic circuits are pathways for electric currents to flow
- Circuits are composed of voltage sources, conductive paths (conductors), and loads
- Types of loads include resistive, inductive, and capacitive loads
- A voltage source provides energy through a potential difference between its positive and negative terminals
- Voltage sources can be AC, which varies sinusoidally, or DC, where the current flows in one direction
Circuit Components
- Passive components consume electric power without introducing energy into the circuit; examples include resistors, capacitors, and inductors
- Active components control current flow, amplifying, injecting, or producing power gain; examples are transistors, thyristors, and triode vacuum tubes
- Electromechanical components utilize electric current or voltage for mechanical functions; examples are DC motors and relays
Types of Circuit Components
- Resistors: oppose current flow, measured in Ohms (Ω)
- Inductors: store energy in a magnetic field when current flows, measured in Henrys (H)
- Capacitors: store electric charge when a potential difference exists, measured in Farads (F)
Essential Parameters of Electric Circuits
- Current (I): measured in Amperes (A), is the flow of electrons through a circuit
- Voltage (V): also known as electromotive force (E), measured in Volts (V), is the potential difference between two points in a circuit
- Resistance (R): measured in Ohms (Ω), is the attribute of a component to resist current flow
Understanding Signals
- Signals are physical quantities that contain information
- Analog signals: have continuous values, representing real-world phenomena like temperature and sound. Analog circuits process these signals
- Digital signals: have only a finite number of distinct values, usually represented by binary values (0 or 1). Digital circuits process these signals
