All, There's a bit of a debate going on over in uk.d-i-y about ac line (mains) voltage being induced into unterminated adjacent wires. We've split into 2 camps, some of us are saying that the inductive coupling of the AC is inducing a low AC current into the unterminated (i.e. 'floating') line. The others are saying this is capacitive coupling due to the metres of dielectric that separate the two wires. Can one of the AC Current theorists on here, please debunk either or both theories with some reasonably technical mumbo jumbo to back it up. Thanks in advance Paul.
