please show all your work. i cant check to see if your correct so please take your time. thanks

Answer 1

Now, V_a - V_q = 20 V = I Req We need I once we have I, Req = 20/I ohm Use Junction Rule and kirchoff Rule at each Junction JL I I_1 + I_2 [Junction = current I_n = current] I_2 = I_4 + I_5 I_1 + I_5 = I_3 I_3 + I_4 = I_1 Now, we can calculate V_a - V_q in 4 ways and set then all = 20 to get 4 equation because than are 4 ways to go from J_1 to J_4 V_a - V_q = 20 = I_1 R_1 - I_3 R_3 gives I_1 + 3I_3 = 20 20 = I_2R_2 + I_4R_4 gives 2I_2 + 4I_4 = 20 gives = I_1R_1 - I_sR_s + I_1 - SI_s + 4I_a = 20 I_2 + SI_s + 5I_s = 20 \r\n Now, we can use (2), (3), (5), (6), (7), (8) to calculate I_1, I_2, I_3, I_4, I_5. We have 5 unknown, so we only need 5 equal 1
