Based on the circuit information, the correct currents are IL = 1 mA, IF = 1 mA, Iin = 1 mA.

Based on the circuit information, the correct currents are IL = 1 mA, IF = 1 mA, Iin = 1 mA.

• A. IL = 1 mA, IF = 1 mA, Iin = 1 mA
• B. IL = 1 mA, IF = 2 mA, Iin = 1 mA
• C. IL = 2 mA, IF = 1 mA, Iin = 1 mA
• D. IL = 1 mA, IF = 1 mA, Iin = 2 mA

Answer: (A)

In a circuit where the same path carries current through all three elements, the current is the same everywhere in that path. The currents labeled IL, IF, and Iin correspond to this single series path, so they must all be equal. Since the given information sets the current through that path at 1 mA, each of IL, IF, and Iin is 1 mA. This is the only arrangement that stays consistent with a single flowing current through all three components. If a node were to split the current (a branch point), you would typically see different values for the branch currents, which would not match these equal currents.
