I need to find the Current through short circuit wire (between a and b).
All the resistor values are same, 100 Ohms
V1 = 5V
V2 = 10V
The Attempt at a Solution
ia*(R2+R4+R1) - ib*(R4) = 5
10 + (ib-ia)*R4 + ib*R3 = 0
ib*(R4+R3) - ib*R4 = -10
After plugging in all the values,
300ia - 100ib = 5
-100ia + 200ib = -10
ia= 0, ib= 0.05 Amps
Current through the circuit is same as ib because the current is not going to flow through R5.
But the problem is I don't think it is possible for ia to be 0...
