Engr 260 -- Circuits & Devices - Test 2 March 26, 2008 Name: _____________________________ Part 2: Solve each of the following problems. 1. Find the current in the 2- Ω resistor using superposition. 2. Use source transformation to find x i . Note: After source transformations, you are allowed to use only one KVL equation . Show all steps As shown in Fig. (a), we transform the dependent current source to a voltage source, (a 15 Ω 40 Ω 5i x 60V + 50 Ω + 10 Ω 60V + (b) 15 Ω 50 Ω 0.1i x 50 Ω
