A syndicated columnist is a writer who produces regular short articles, typically on a specific theme or subject, and sells them to a service that distributes them for her. The distribution normally spans many publications. Newspaper syndicated services normally distribute the material over a wide geographic regions.
Technically, VArs are the product of the rms voltage and current, or the apparent power, multiplied by the sine of the phase angle between the voltage and the current. Or in mathematical terms, the reactive power Q, (measured in units of volt-amperes reactive or VAr), is given by. Q = Vrms * Irms * sin(Ï)
Modern varistor schematic symbol. A varistor is an electronic component with an electrical resistance that varies with the applied voltage. Also known as a voltage-dependent resistor (VDR), it has a nonlinear, non-ohmic currentâvoltage characteristic that is similar to that of a diode. In contrast to a diode however, it has the same characteristic for both directions of traversing current.
