Electronics and Digital Systems

Practice flashcards covering key concepts in electronics and digital systems based on the lecture notes.

Voltage

The potential for charge to move, measured in volts.

Current

The amount of charge flow, measured in amps.

Resistance

A wire's opposition to flow, measured in ohms.

Ohm's Law

The relationship between voltage (V), current (I), and resistance (R) given by V = IR.

Electrical System

A system involving the movement of charged electrons through wires, such as a lamp.

Analog System

A system where voltages can assume infinite values, like 0.15, 0.2, etc.

Digital System

A system treated as having two values, high and low, typically built with switches.

Transistor

A small switch with no mechanical parts, used in digital circuits.

Control Input

The terminal that controls an electronically controlled switch.

pMOS Transistor

A type of transistor that conducts when its control input is 0.

nMOS Transistor

A type of transistor that conducts when its control input is 1.

Circuit

A path through which electrical current flows.

Switch

An electronic device that conducts between two terminals when configured to 'on'.

Ground (0 V)

A reference point in an electrical system, usually represented by three line segments.
