Definition

1. Noun:
   • Potential drop, voltage drop: In electricity, "sụt thế" refers to the decrease in electric potential (voltage) between two points in a circuit, caused by the resistance or impedance of the components.

Usage Examples

• Noun:
  • Sụt thế trên dây dẫn có thể làm giảm hiệu điện thế đến thiết bị. (The voltage drop on the conductor can reduce the voltage reaching the device.)
  • Chúng ta cần tính toán sụt thế để đảm bảo hệ thống hoạt động hiệu quả. (We need to calculate the potential drop to ensure the system operates efficiently.)

Advanced Usage

• Technical Specification: Often used in technical documents, circuit design, and electrical engineering discussions.
  • Sụt thế cho phép trong mạch này là 5%. (The allowable voltage drop in this circuit is 5%.)
• Cause and Effect Analysis: Used to describe the reason for a device's underperformance.
  • Đèn bị mờ do sụt thế trên đường dây quá lớn. (The light is dim due to an excessive voltage drop on the line.)
