MDCAT Physics MCQ #431

  1. Question 1

    Q1. The equivalent resistance of two resistors in parallel is

    • A) R1 + R2
    • B) R1*R2 / (R1 + R2)
    • C) (R1 + R2) / (R1*R2)
    • D) 1 / (1/R1 + 1/R2)

    Answer: R1*R2 / (R1 + R2)

    Explanation: 1/Req = 1/R1 + 1/R2, simplifying yields Req = R1*R2 / (R1 + R2), a valid formula for parallel resistors.
