Back EMF Demonstration

The video tutorial explains the concept of back EMF in electric motors, highlighting its role in reducing current when the motor is rotating. It discusses the absence of back EMF during motor startup, leading to higher current. A practical example using a miter saw illustrates how back EMF affects circuit load and light brightness, emphasizing the increased load and decreased current available for other devices when the motor is starting up.
