1. The problem statement, all variables and given/known data for S1,S2,S3,S4 are all closed at the long time find the current in each resistor 2. Relevant equations 3. The attempt at a solution why I3 is not = i2? the solution of this question is 24-28I1-I212-12=0 7I1-32=3-----(1) 12-12I2-163=0 3I2+43=3 ---(2) I1+I2-I3=0---(3) I1=0.492 I2=0.148 I3=0.639 why there are 3 current in 2loop and I2 is not =I3 and why at the top loop the equation is not 24-28I1-[I1-I2]12-12=0???
