Problem
A constant current source supplies IS=6.0A into junction J1. The current splits into two paths carrying currents I1 (through a 2Ω resistor) and I2 (through a 3Ω resistor) before arriving at junction J2. At J2, an independent device draws 1.0A out of the circuit. The remaining current passes through a 1Ω resistor back to the negative terminal of the sources, completing the circuit at junction J3. What is the value of I2?
(a) 3.6A
(b) 2.4A
(c) 4.0A
(d) 2.0A
