 Recently, I needed a low-power circuit for one of my battery-operated projects.
-Much of the system's power savings depended on its ability to switch off power
-to components, such as servos, electronically when not needed. That's how I
-stumbled upon MOSFETs, transistors capable of controlling circuits operating at
-voltages far above their own.
