1. An arrangement for accurately measuring the source voltage of a high-impedance source while supplying a variable burden load comprising:

  • a current-sensing element, the series combination of said current-sensing element and the variable burden being connected to the high-impedance source; and

    a voltage regulator being connected with the variable burden so as to maintain a constant voltage across the variable burden, the voltage developed across said current-sensing element accurately representing the voltage of the high-impedance source, said current-sensing element comprising a current transformer.
