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)
Varistor Tutorial. The varistor is a passive two-terminal solid state semiconductor device that is used to provide protection to electrical and electronic circuits. Unlike the fuse or circuit breaker which offers over-current protection, the varistor provides over-voltage protection by means of voltage-clamping in a similar way to the zener diode.
