NOTE
Alternate Loads -- Any reasonable combinations of resistance, capacitance, and inductance maybe used to
satisfy the load requirements, provided that the ratio of resistance to reactance provides the specified power
factor and a variable auto transformers used to allow adjustment of the applied load current. In this method the
entire dummy load fixture must be calibrated by means of the external voltmeter/ammeter.
