The video tutorial explains the issues caused by voltage spikes in electronic switches, particularly in circuits with inductors. It introduces diodes as a solution to protect delicate components like transistors from damage. The tutorial covers the functionality of diodes, including their IV curve, and how they provide a path for current to prevent kickback. It emphasizes the importance of using diodes in circuits with inductors, such as motors or solenoids, to ensure safe operation and protect the circuit components.
