The term " return electrode " is also technically incorrect since alternating electrical currents refer to alternating polarity, a circumstance that results in bidirectional flow across both electrodes in the circuit.

MacKenzie devised MacKenzie buckets which are plasma sources created by lining vacuum chamber walls with permanent magnets of alternating polarity to suppress plasma electron losses, that are widely used to this day.
13.
Since the pickups of 5-way switch-equipped guitars are wound with alternating polarities ( N-S-N or S-N-S ), some amount of phase cancellation occurs, effectively creating a spaced humbucking pair, resulting in a characteristic sound.
14.
When a piece of tissue is held by the forceps, the RF alternating polarity electrical current oscillates between the two forceps tines, heating the intervening tissue by the previously described synchronous oscillation of intracellular ions.
15.
Although Mars has no evidence of a structured global magnetic field, observations show that parts of the planet's crust have been magnetized, suggesting that alternating polarity reversals of its dipole field have occurred in the past.
16.
They can also be used to remove particulate matter from air streams by first charging the air, and then passing the charged stream through a comb of alternating polarity, to deposit the charged particles onto oppositely charged plates.
17.
Matthews and Fred Vine were then about to announce a discovery of lasting importance : They had towed a magnetometer across a ridge in the Indian Ocean and shown that the sea floor was magnetized in stripes of alternating polarity.
18.
In power supply design, a bridge circuit or bridge rectifier is an arrangement of diodes or similar devices used to rectify an electric current, i . e . to convert it from an unknown or alternating polarity to a direct current of known polarity.
