  1. To find the current in a 20 Ω resistance connected in a circuit, Norton's theorem is used. IN = 7.5 A. The current though 20 Ω resistance.

  2. A.
    is 7.5 A
    B.
    is less than 7.5 A
    C.
    may be 7.5 A or less
    D.
    may be 7.5 A or more or less

    Answer : Option B

    Explanation :

    Norton's equivalent is as shown in figure. Some current will flow through RN. There-fore, current through 20Ω resistance is less than 7.5 A.
