Homework Help: Resistance of parallel resistors

  1. Mar 2, 2004 #1
    If resistors of 5 ohm, 20 ohm, 40 ohm, and 50 ohms are parallel with each other, the equivalent resistance would most nearly be how many ohms?

    Have you no expression for the resistance of parallel resistors?

    Well, do you have options? Sounds like a multiple choice question. Nearly how many ohms?

    try 1/Rx = 1/R1 + 1/R2 + 1/R3 +1/Retc... !
