Diodes and Transistors

The video tutorial explains the role of transistors and diodes as semiconductor devices. It describes how these devices, made from enhanced natural materials, control electric currents. Diodes, the simplest semiconductor devices, allow current to flow in one direction, similar to a one-way valve. They are used in various applications, including battery protection and converting AC to DC. Some diodes, like LEDs, emit light and are used in screens. Transistors, with three silicon layers, act as switches and amplifiers, boosting signals. They were pivotal in the development of transistor radios and are integral to modern computer chips. Despite their small size, transistors and diodes have significantly transformed technology and daily life.
