Active components rely on a source of energy (usually from the DC circuit, which we have chosen to ignore) and usually can inject power into a circuit, though this is not part of the definition. [4] Active components include amplifying components such as transistors , triode vacuum tubes (valves), and tunnel diodes .
Active component may refer to: Active duty, full-time service in a military force; Active device, an electronic device that amplifies a signal or produces a power gain;
For a circuit to be referred to as electronic, rather than electrical, generally at least one active component must be present. The combination of components and wires allows various simple and complex operations to be performed: signals can be amplified, computations can be performed, and data can be moved from one place to another.

ActiveX is a deprecated software framework created by Microsoft that adapts its earlier Component Object Model (COM) and Object Linking and Embedding (OLE) technologies for content downloaded from a network, particularly from the World Wide Web. [1]
An active load or dynamic load is a component or a circuit that functions as a current-stable nonlinear resistor. Circuit design. In circuit design, ...
The role of the substrate in power electronics is to provide the interconnections to form an electric circuit (like a printed circuit board), and to cool the components.. Compared to materials and techniques used in lower power microelectronics, these substrates must carry higher currents and provide a higher voltage isolation (up to several thousand vo

The active circuit consists of an impedance translating stage and an optional amplification stage. This arrangement is especially useful for constructing low frequency antennas which, due to budgetary, spatial, or practical requirements, must be kept compact. Power for the active components may be supplied by batteries, a filtered power supply ...
