1 EE2120 TAKE HOME QUIZ February 28, 2001 NAME (please print) SSN 0 1 2 3 4 5 6 7 s I 1 R 2 R 3 R 4 R 5 R 6 R 7 R 8 R 9 R 10 R 11 R 12 R The ﬁgure shows a cube of resistors driven by a current source. Node zero is assumed to be the reference node. The goal is to compute all the node voltages { V 1 ,V 2 ,..., V 7 } . Each student has a set of values for the resistors and the current source. 1. (10PTS)Write all seven node equations in the form g k 1 V 1 + g k 2 V 2 + ... + g k 7 V 7 = i k ; k =1 , 2 ,..., 7 Be sure to use values of resistors and current source assigned to you. You can give your answer as a matrix G =[ g kj ] and a vector I =[ i k ]

(10PTS) USE AS LOOP CURRENTS THE CURRENTS ASSOCIATED TO THE LOOPS 72107,76127, 76547, 74327,65016,54305, to write six independent loop equa-tions of the form r k 1 I 1 + r k 2 I 2 + ... + r k 6 I 6 = v k ; k = 1 , 2 ,... , 6 You can give your answer as a matrix R = [ r kj ] and a vector V = [ v k ]. Make sure that you use the numerical values assigned to you. 3. (5PTS)Express the voltage at node 7 as a function of the loop currents in the form V 7 = c 1 I 1 + c 2 I 2 + ... c 7 I 6...
