Introduction to Electronics


Electronics is the field of manipulating electrical currents and voltages using passive and active components that are connected together to create circuits. Electronic circuits range from a simple load resistor that converts a current to a voltage, to computer central-processing units (CPUs) that can contain more than a million transistors. The following indices and documents provide a basic reference for understanding electronic components, circuits, and applications.

Reference Documents

Basic electronic quantities
Definitions of charge, current, voltage, and impedance.
Index of electronic components
Includes common circuit symbols.
Index of detection electronics
Common detection electronics including digital oscilloscope, gated integrator, lock-in amplifier, and pulse counting.
Computer data acquisition (DAQ)
An introduction to data-transfer methods and computer plug-in DAQ boards.
