On the diagram, mark the directions of the currents I1, I2, I3, and I4 through the respective resistors R1,
R2, R3, and R4.
B. Write down the node rule equation (involving currents) relating I1, I3, and I4. Note that I2 is not included
in this!
 
C. Write down all the loop rule equations (involving voltages) for this circuit. Use symbols only (not the values
for the resistances and EMFs given later in this problem).
D. Solve your loop and node equations to determine the currents I1, I2, I3, and I4. The numerical values of the
EMFs are EmfA = 6 V and EmfB = 3 V. The resistors are all identical and have a value of 100 Ω each.
