Multiple Choice

A 4.0-Ω resistor is connected with a 12-Ω resistor and both of these are connected across an ideal dc power supply with voltage V as shown in the figure. If the total current in this circuit is I = 2.0 A, what is the current through the 4.0-Ω resistor?

A) 2.0 A
B) 2.5 A
C) 0.5 A
D) 3.0 A
E) 1.5 A
