Electronics

[riya]

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.
