No. You would need to check the voltage between the two ends of a wire, which is near zero, and *that* voltage would be transformed to the secondary (low-voltage) side, not the voltage between the two wires. Furthermore, the fields from the two conductors with opposite current direction nearly cancel out, which reduces the effect even more. cu Michael -- Some people have no respect of age unless it is bottled.
