Explanation
The core image of วงจร is a connected path or sequence that completes a full round. In electrical and electronic contexts, it means a circuit through which current or signals travel. For natural processes, biological development, and similar phenomena, it means a cycle. It can also describe a recurring chain of causes and effects, as in วงจรหนี้ (“cycle of debt”) or วงจรความรุนแรง (“cycle of violence”). The word is commonly followed by what the circuit or cycle relates to, as in วงจรไฟฟ้า (“electrical circuit”). กล้องวงจรปิด is a fixed, everyday term meaning “security camera” or “CCTV camera.”
Usage
It is used for circuits in discussions of electronics, computers, machinery, and repairs. In science and education, it describes processes such as the water cycle and biological life cycles. News and social commentary also use it for recurring patterns such as cycles of debt or violence.
Caution
วงจร does not normally mean merely a circular shape or a ring; it implies a connected path, sequence, or causal process. Use วงกลม for a geometric circle. Also, รอบ emphasizes one round or occurrence, whereas วงจร emphasizes the complete system or process that forms a cycle.
