An expertly remodeled master bathroom will provide years of pleasure and comfort. But do an amateur job and youâll be reminded of the fact every day. Itâs a tricky space, unfortunately, with lots of moving parts crammed into a tight footprint, not to mention the volumes of water ready to exploit any and all leaks.
A voltage source is a two terminal device which can maintain a fixed voltage. An ideal voltage source can maintain the fixed voltage independent of the load resistance or the output current. However, a real-world voltage source cannot supply unlimited current. A voltage source is the dual of a current source.
Power supplies are vital in the world of electronics. The most common power source is the household 110V to 120V AC outlet (240V in some other countries). There are several different power supply designs for converting AC to the necessary DC for most electronic circuits. This article presents various vacuum tube power supply designs and some solid-state versions.
