循環 emphasizes the act of circulating, while 回路 refers to the route or system through which that circulation happens.
経けい路ろN1sense 3
経路 is a more general word for a route or path, while 回路 specifically implies a closed loop that returns to its starting point.
ループ sense 3
ループ is a casual loanword for a loop used especially in everyday or computing contexts, while 回路 sounds more technical and structural.

回路 is the native Japanese term for an electric circuit and is far more common in technical writing, while サーキット is a loanword rarely used for this sense outside specialist jargon.

noun

biological cycle; metabolic cycle

biology

Biology and biochemistry use, especially for named cycles such as the citric acid/Krebs cycle.

noun

loop; cycle; closed path

Broader use for a path or route that circulates or returns to itself; often technical and more formal than everyday ループ.
