Introduction to Electric Motor Control
- Action: Cover the right side of the circuit with your hand. Try to guess whether the motor runs or stops based on the left-side inputs.
- PDF Tip: Use a PDF annotation tool (like Adobe Acrobat or Foxit) to draw the flow of current with a red line. This virtual "tracing" builds troubleshooting skills.
