To find the value of current I, we will apply Kirchhoff's Current Law (KCL) at each junction in the circuit diagram. KCL states that the sum of currents entering a junction must equal the sum of currents leaving that junction. Step 1: Apply KCL at the first junction (leftmost). Two currents, 3 A and 1.5 A, are entering this junction. Let the current leaving this junction be I_1. I_1 = 3 A + 1.5 A I_1 = 4.5 A Step 2: Apply KCL at the second junction (where I_1 splits). Current I_1 (4.5 A) is entering this junction. Current 0.5 A is leaving, and another current, let's call it I_2, is also leaving. I_1 = 0.5 A + I_2 4.5 A = 0.5 A + I_2 I_2 = 4.5 A - 0.5 A I_2 = 4.0 A Step 3: Apply KCL at the third junction (where I_2 and 2.5 A meet). Current I_2 (4.0 A) and 2.5 A are entering this junction. Let the current leaving this junction be I_3. I_3 = I_2 + 2.5 A I_3 = 4.0 A + 2.5 A I_3 = 6.5 A Step 4: Apply KCL at the fourth junction (final junction where I_3 splits into I and 1.5 A). Current I_3 (6.5 A) is entering this junction. Currents I and 1.5 A are leaving this junction. I_3 = I + 1.5 A 6.5 A = I + 1.5 A I = 6.5 A - 1.5 A I = 5.0 A The calculated value for I is 5.0 A. Comparing this with the given options: [A] 0.3 A [B] 0.5 A [C] 1.3 A [D] इनमें से कोई नहीं (None of these) Since 5.0 A is not among options A, B, or C, the correct option is [D]. The final answer is D. 3 done, 2 left today. You're making progress.
