I am very confused with this problem, I know that I have to reduce the circuit, and we will end up with 2 resistor 1 in each side and the current in the middle, I know that I have to use current division, how do I know according to this problem which Z1 and Z2 will be. The io is on the right side.. The io will be the same in the left and right side... I need steps for this problem please
1. Set up the circuit shown using a function generator for the source voltage Vs. Set the function generator to 10 V P-P at 100 Hz (You need to set the Vp-p on the function generator to 5V).

Please answer, thank you! The circuit is composed of resistors with a voltage sources. Solve for the branch currents (I1 to I5) as indicated in the figure using Kirchoffs Laws. Current are assumed. See attached figure.
Need to use kirchhoffs voltage and circuit laws. But not understanding. Need to find V500,V50,V150,V250,V1000,P1000.
