Solution of ECE 300 Test 2 F09 1. In the partial circuit below V in = 10V , V 2 = 2V , V 4 = 7V . Find the numerical values of V 3 and V out . V in + V 4 V 2 + V 3 = 0 V 3 = V in V 4 + V 2 = 10V 7V + 2V ( ) = 1V V in + V 4 + V out = 0 V out = V in V 4 = 10V 7V = 3V 2. In the circuit below, R 1 = 5 Ω , R 2 = 10 Ω , R 3 = 20 Ω and R 4 = 2 Ω . (a) How many nodes are there in this circuit? 4 (b) What is the numerical equivalent resistance R eq between terminals a and b ? R eq = R 3 + R 4 + R 2 ( ) || R 1 = 20 Ω + 2 Ω + 10 Ω ( ) || 5 Ω = 20 Ω + 12 Ω || 5 Ω = 23.53 Ω 3. In the partial circuit below I in = 12A , R 1 = 8 Ω , R 2 = 3 Ω and R 3 = 5 Ω . Find the numerical value of I 3 . I 3 = I in R 1 || R 2 R 1 || R 2 + R 3 = 12A 8 Ω || 3 Ω 8 Ω || 3 Ω + 5 Ω = 12A 2.182 Ω 2.182 Ω + 5 Ω = 3.65A
