Why Are Resistors Used

The video tutorial explains the role of resistors in circuits, comparing them to a kink in a pipe that reduces water flow. It describes how resistors cause energy loss, resulting in heat, and demonstrates this with a thermal imaging camera. The tutorial also covers calculations for selecting appropriate resistor values for an LED circuit to prevent burnout or dim lighting. The video concludes with a summary of the key points discussed.
