Por qué se utilizan las resistencias en los circuitos

The video tutorial explains how resistors impede electron flow in circuits, similar to how a kink in a pipe restricts water flow, causing energy loss and pressure drop. It describes how resistors cause voltage drops and dissipate energy as heat, visible through thermal imaging. The tutorial also covers calculating appropriate resistors for an LED to prevent damage or insufficient brightness, emphasizing the importance of matching resistance to current requirements.
