1. The problem statement, all variables and given/known data Use mesh analysis to find the current through the 4 Ohm resistor. 2. Relevant equations 3. The attempt at a solution From this circuit I managed to work out the three mesh equations using mesh analysis. Mesh 1 = 7I1 + 4I2 = 67 Mesh 2 = -4I1 + 15I2 - 6I3 = 152 Mesh 3 = -6I2 + 13I3 = 74 Are these mesh equations correct. From this point in the question how do I calculate the current through the 4 ohm resistor. I know you use simultaneous equations but I can't get the correct answer. Please help.
