Definitions and Measurement of Power Factor
Definitions and Measurement of Power Factor

... Reactive power, and Apparent power are applied to steady-state alternating current circuits in which the voltages and currents are non-sinusoidal. Today it is characteristic in most parts of the applications that the current and voltage are nonsinusoidal. The origin of these problems are the followi ...

... reported in [7]. This result shows that the VCO operate correctly at low bias voltages. A common figureof-merit in digital design to save power is by applying a bias voltage lower than the sum of both basic threshold voltages, (VTn+⏐VTp⏐).

Electrical ballast



An electrical ballast is a device intended to limit the amount of current in an electric circuit. A familiar and widely used example is the inductive ballast used in fluorescent lamps, to limit the current through the tube, which would otherwise rise to destructive levels due to the tube's negative resistance characteristic.Ballasts vary in design complexity. They can be as simple as a series resistor or inductor, capacitors, or a combination thereof or as complex as electronic ballasts used with fluorescent lamps and high-intensity discharge lamps.
