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)
Voltage is a measure of the difference in electrical energy between two parts of a circuit. The bigger the difference in energy, the bigger the voltage. Voltage is measured in volts. The symbol for volts is V. For example, 230V is a bigger voltage than 12V.
