@tech.vectors: A MOSFET is a switch with no moving parts — and almost no current into the gate. Push the gate past its threshold and an electric field pulls a channel into existence between source and drain. Crank the drain voltage and that channel pinches off, current levels out, and you've got the building block behind every chip you own. 🔋 Sound on. 🎧 #electronics #semiconductors #mosfet #engineering #embeddedsystems
