    Answer:

    Step-by-step explanation:

    let r1=2ohms r2=3 ohms

    if resistors are connected in series

    r=r1+r2

    r=2+3

    r=5 ohm

    if resistors are in parallel

    1/r=1/r1 + 1/r2

    1/r=1/2 + 1/3

    1/r=3/6 + 2/6

    1/r= 5/6

    r=6/5

    r=1.2 ohms

    ∴The least resistance is found when they are connected in parallel. The least resistance is 1.2 ohm
