    Answer:

    0.6 A

    Explanation:

    Applying,

    I = E/(R’+r)……………….. Equation 1

    Where I = curent or circuit supply, R’= equivalent external resistance, r = internal resistance.

    From the question,

    Given: E = 12 Volt,

    IF the three resistors are connected in series, R’ = (3+7+10) ohm = 20 ohm,

    r = neglible.

    Substitute these values into equation 1

    I = 12/(20)

    I = 0.6 A
