noun🔗Share정류자An electrical switch, in a generator or motor, that periodically reverses the direction of an electric current."The small motor in my son's toy car has a commutator that flips the current, allowing the wheels to keep spinning in the same direction. "내 아들의 장난감 자동차에 있는 작은 모터는 전류를 뒤집는 정류자를 가지고 있어서 바퀴가 같은 방향으로 계속 회전할 수 있습니다.electronicsdevicemachineelectrictechnologyChat with AIVocabulary GamePractice Reading
noun🔗Share교환자A binary map in a given group G, given by [g, h] = ghg−1h−1, where g and h are elements of G, which yields the group's identity if and only if the group operation commutes for g and h."In group theory, the commutator of two elements tells us how much those elements fail to commute; if the commutator equals the identity element, then the elements commute perfectly. "군론에서 두 원소의 교환자는 해당 원소들이 얼마나 교환하지 못하는지 알려줍니다. 교환자가 항등원과 같으면 해당 원소들은 완벽하게 교환합니다.mathgrouplogicChat with AIVocabulary GamePractice Reading
noun🔗Share교환자A binary map in a given ring R, given by [a, b] = ab − ba, where a and b are elements of R, which yields the ring's zero element if and only if the multiplication operation commutes for a and b."In abstract algebra, the commutator [x, y] = xy - yx shows us how much two elements x and y fail to commute; if the commutator equals zero, then x and y commute perfectly. "추상 대수학에서, 교환자 [x, y] = xy - yx는 두 원소 x와 y가 얼마나 교환에 실패하는지 보여줍니다. 교환자가 0이면 x와 y는 완벽하게 교환합니다.mathlogictechnicalsciencesystemChat with AIVocabulary GamePractice Reading
