Faulted DC Circuit
A 5-ohm distributed resistor is connected between the positive terminals of two ideal 5-volt DC batteries. The negative terminals of the batteries are connected together.
There is a 1-ohm fault (unintended connection) from some point on the distributed resistor to the negative bus. The resulting currents (both magnitude and direction) are illustrated in the above diagram.
Determine how many ohms of distributed resistance there are to the LEFT of the fault point.
