O condutor variável no circuito foi ajustado para otimizar a distribuição de energia.
This is primarily technical terminology used in electrical engineering, physics, and electronics education in both Brazil and the USA. The term is most common in academic and professional settings rather than everyday conversation. In Brazil, the concept is taught extensively in engineering programs (Engenharia Elétrica) and is essential for understanding power distribution systems.
