rẽ mạch
Definition
- Noun (Technical/Engineering):
- A shunt / a bypass / a derivation: A component or circuit path that provides an alternative route for electrical current, typically to divert a portion of the current away from a main circuit or device for measurement or protection purposes.
Usage Examples
- Noun:
- Sử dụng rẽ mạch để đo dòng điện cao. (Use a shunt to measure high current.)
- Rẽ mạch bảo vệ thiết bị khỏi quá tải. (The bypass protects the device from overload.)
Advanced Usage
- In electrical engineering, a "rẽ mạch" often refers specifically to a shunt resistor used for current measurement.
- Giá trị của điện trở rẽ mạch phải rất chính xác. (The value of the shunt resistor must be very precise.)
Variants and Related Words
- Mạch rẽ (n): a branch circuit, a diverted circuit path.
- Dòng điện chia ra ở mạch rẽ. (The current divides at the branch circuit.)
Synonyms
- Shunt: A device that creates a low-resistance path for electric current.
- Bypass: An alternative path that avoids a main route.
- Derivation: The act of diverting or drawing off, or the path created.
Notes on Usage
- "Rẽ mạch" is a specialized technical term primarily used in fields like electrical engineering and electronics. It is not common in everyday conversation.
- The term directly describes the function of diverting or branching an electrical current.
