Working Principle of MOSFET

A Metal-Oxide-Semiconductor Field-Effect Transistor, or MOSFET, is one of the most widely used types of transistors in modern electronics. It’s a three-terminal semiconductor device that can be used either as a switch or an amplifier. Understanding how MOSFETs work and their characteristics is vital for anyone working with electronics. In this blog, we will break …
