[ noun ] (physics,electricity) electrical conduction through a gas in an applied electric field

Used in print

(Raymond C. Binder et al., editors, Proceedings...)

Experiments were made on an electric arc applying a porous graphite anode cooled by a transpiring gas ( Argon ) .

Thus , the energy transferred from the arc to the anode was partly fed back into the arc .

Thus , the energy transferred from the arc to the anode was partly fed back into the arc .

It was shown that by proper anode design the net energy loss of the arc to the anode could be reduced to approximately 15 % of the total arc energy A detailed energy balance of the anode was established .

The ball went off in a majestic arc , an out-of-bounds slice .

(R. P. Jerrard, "Inscribed squares in plane curves"...)

But **f is just the curve **f translated without rotation through a small arc , for **f is always obtained by rotating C through exactly 90 ` .

The arc is itself a segment of an analytic curve .

A continuous change in t through an amount e results in a translation along an analytic arc of the curve **f .
