Question

    If n resistors with R Ω each as resistance are

    connected in parallel, then the equivalent resistance of the network is:
    A 1 Correct Answer Incorrect Answer
    B 2 Correct Answer Incorrect Answer
    C 3 Correct Answer Incorrect Answer
    D 4 Correct Answer Incorrect Answer

    Solution

    When the resistances are connected in series, the equivalent resistance is given by The equivalent resistance is greater than the largest resistance in the series circuit  R req = R1+ R2+ R3 ....+ Rn When the resistances are connected in parallel, the equivalent resistance is given by The equivalent resistance is lesser than the smallest resistance in the series circuit Calculation:  1/Rreq =  1/R1 + 1/R2 + ......... 1/Rn If n resistances are in parallel, equivalent resistance will be: Rn =  R/n
