Watts, Vars and VA
(VAR, volt-amps reactive) Apparent power (VA) is the easiest to measure; it is what you get when you measure the rms volts with one meter and the rms amps with another meter and multiply the two. P = V x A = VA Equation 1; Apparent Power The measurements must be made with "True RMS" meters. Unfortunately,
