KCL & KVL:
The Attempt at a Solution
Ok folks I am not sure where to go from here. Someone suggested changing the 144V to its Thevenin equivalent, which I have done below. I know that I am supposed to apply KCL at each node A,B, and C. And then I represent each current in terms of voltages. Now I am a little confused as to how to proceed.
I am trying got convince myself that R1, R2, and R3 are in parallel because their leads are all connected, but I am not sure yet. The voltage drop across R1 is definitely just VA since I can pass from A across the resistor and directly to ground. But for R2 and R3, I feel like the voltages at B and C need to be considered.
