What is a transistor

The video tutorial explains the two main types of transistors: bipolar and field effect, focusing on the bipolar type. It covers their functions as switches and amplifiers, the construction differences between low and high power transistors, and the importance of heat management. The video also details how to identify transistors using their pins and datasheets, and demonstrates their use in circuits as switches and amplifiers. It concludes with an explanation of current gain and its significance.
