    Question

    Three elements having conductance G1, G2 and G3 are connected in parallel. Their combined conductance will be:

    A.

    1/(1/G1+1/G2+1/G3)

    B.

    (G1G2+G2G3+G3G1)/(G1+G2+G3)

    C.

    1/(G1+G2+G3)

    D.

    G1+G2+G3

    Correct option is D


    · Conductance (G) is the reciprocal of resistance (R) :
    G=1/R
    · In a parallel connection, the total conductance is the sum of individual conductance, similar to how resistances add in series:
    G total  = G1+G2+G3
