1. A resistance measurement circuit used in a power circuit, comprising:

  • an analog to digital converter (ADC) electrically connected to the power circuit to receive output voltage from the power circuit;

    a signal control module electrically connected to the ADC; and

    a potentiometer electrically connected to the signal control module, wherein the ADC converts the output voltage from the power circuit to corresponding digital signals, the signal control module compares two consecutive digital signals to establish a voltage difference according to the comparison, if the voltage difference is outside a predetermined voltage range, the signal control module controls the potentiometer to adjust the resistance and the output voltage from the power circuit until the voltage difference is within the predetermined voltage range.
