Understanding Characteristics of Series Motor — Lesson 2

This lesson covers the fundamental characteristics of a series motor. The main focus is on the relationship between speed and current in a series motor. It is explained that the current in a series motor is proportional to the square root of the torque (T). This relationship is crucial in understanding the operation and performance of series motors in various applications.
