    Answer:

    2Ω

    Explanation:

    If a 18Ω resistance is cut into three equal parts each of the resistance will be 18Ω/3 = 6Ω

    Equivalent ratio in parallel is expressed as:

    1/R = 1/6 + 1/6 + 1/6

    1/R = 3/6

    Cross multiply

    3R = 6

    R = 6/3

    R = 2Ω

    Hence the required equivalent resistance is 2Ω
