Step 1: Analyze the bridge network and identify the given values.
The circuit is an unbalanced Wheatstone bridge.
The voltage source is V=54 V.
The total current from the source is given as Itotal=9 A.
The resistors are:
RXA=2Ω (top-left)
RAY=4Ω (top-right)
RXB=1Ω (bottom-left)
RBY=3Ω (bottom-right)
RAB=32Ω (middle, bridge resistor)
There is a contradiction in
