Options
- A1 5 ~A
- B2 5 ~A
- C1 4 ~A
- D3 4 ~A
Correct answer
B. 2 5 ~A
Step-by-step solution
Parallel branch simplification: With identical 3 V sources and 3 resistors in parallel, the Norton equivalent conductance is 1 3 + 1 3 = 2 3 S, so equivalent resistance is R_ eq = 3 2 . Equivalent current source is 3 V 3 + 3 V 3 = 2 A , yielding V_ eq = 2 A 3 2 = 3 V . Total circuit analysis: The 6 resistor is in series with the 3 2 equivalent resistance, giving total resistance 7.5 . By Ohm's law, current is I = 3 V 7.5 = 2 5 A . Final current: 2 5 A
