MCAT Question of the Day


  • Q:

    Which of the following provides a plausible explanation for why resistance of resistors add when they are in series rather than in parallel?

     

    A

    Total resistance of a set of resistors has no relation to the length of the resistor, thus it is intuitive that adding in series is most accurate for adding resistors

    B

    Increased area of a resistor increases its resistance, and adding resistors in series functionally increases cross-sectional area

    C

    Resistors in parallel increase distance that current must travel, thus it is intuitive that this would decrease resistance (and resistors in series would add resistance)

    D

    Increased length of a resistor increases its resistance and adding resistors in series is functionally equivalent to adding length to the resistor
