"THREE VOLTMETER METHOD"



Original poster: Ed Phillips <evp-at-pacbell-dot-net> 

Forgot to mention that the three voltmeter method gives the magnituce
of the load reactance but not the sign (in other words could be an
inductor or a capacitor).  Easiest way to find out is to put a big
capacitor (say 10 ufd) in series with the test circuit.  If the current
goes up the load is inductive and if it goes down it is capacitive.
