Abstract
A method and apparatus determines the output voltage of a power source necessary to produce a desired lamp voltage at an incandescent lamp remote therefrom using voltage and current measurements at the power source for a circuit including a series resistor and a circuit without the resistor. Estimated circuit resistances are determined according to an algorithm that calculates the power source output voltage necessary to produce a desired lamp voltage at the lamp.
