A displacement current appears when an AC voltage
is put over a capacitor. The cap ensures a coupling between
the two ends of the wire. The displacement current is
-- defined -- as /epsilon_0 /partial /phi / \partial /t (I hope
you can read this... it's Knuth's teX :), where /phi is the
electrical fluxdensity between the plates. There is no real
electron current between the plates of course. Since the
dimensions of above variable equals those of a current, it
is named a 'current'.

Hi. I am new to this group and this is my first question? What
is "displacement current"? Is it electron current?
