  2. Correction:

    R1 = R2 = R3 = 27/3 = 9 Ohms, each.

    When connected in parallel:
    Re = 9/3 = 3 Ohms.

  3. given:
    A wire of uniform thickness with a resistance =27 ohm
    equivalent resistance in parallel
    resistance of each wire=27/3=9
    therefore when in parallel equivalent resistance=
    therefore rp=3 ohm
