gardrâh, barqrâh (#)
1) General: A closed, usually circular line that goes around an
object or area.
From O.Fr. circuit, from L. circuitus "a going around," from stem of circuire, circumire "go around," from circum "around," → circum- + -ire "to go" (cf. Gk. ienai "to go," Skt. eti "goes," O.Pers. aitiy "goes," Av. aeiti "goes," Mod.Pers. âyad "comes," PIE *ei- "to go, to walk."
Gardrâh, from gard "turning round, revolving,"
from gardidan "to turn, to change"
(Mid.Pers. vartitan, Av. varət- "to turn, revolve,"
Skt. vartati, L. vertere, O.H.G. werden "to become;"
PIE *werto, *wer-)
+ râh "way, path," from
Mid.Pers. râh, râs "way, street" (Mid.Pers. rah, ras "chariot"),
from Proto-Iranian *rāθa-; cf.
Av. raθa- "chariot;" Skt. rátha- "car, chariot,"
rathyā- "road;" L. rota "wheel," rotare "to revolve, roll;"
Lith. ratas "wheel;" O.H.G. rad; Ger. Rad; Du. rad;
O.Ir. roth; PIE *roto- "to run, to turn, to roll").
Fr.: circuit électrique
Physics: A closed path followed by an → electric current; a number of → conductors interconnected for the purpose of carrying an electric current.

Fr.: circuit intégré
A circuit whose components are found on a single semiconductor substrate.
Fr.: circuit résonnant
An electrical circuit containing both capacitance and inductance in such a way that a certain periodic electric oscillation will reach maximum amplitude.
A relatively low → resistance contact, usually accidental, between two points of an → electric circuit with initially different → potential. A short circuit brings about a flow of excess → electric current that can damage the circuit and present a danger for the user.
Gardrâhband, literally "link, bind, bond in circuit," from gardrâh, → circuit, + band, → band.
Fr.: circuit atténuateur
A low-pass filter designed to reduce the amplitude of a ripple while freely passing the direct current obtained from a rectifier or direct-current generator. Also known as smoothing filter.
Fr.: circuit déclancheur
A circuit in which a specific predetermined action is initiated by an input pulse.
