Voltage Divider Polarity

  1. Jan 17, 2015 #1
    What polarity does the output of a voltage divider have?, do the resistors only decrease the original voltage?

    Are resistors active or passive components?

    They are passive because they do not produce energy. Why?

    Is a passive component going to do anything to the polarity of the circuit?

    Have you looked at the theory / equation for a Voltage divider (potential divider)? What gave you the impression that the PD could change polarity if the reference zero is the same for input and output?
