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.
Since laser diodes and high-power LEDs are usually driven by current sources instead of. voltage sources, letâs take a brief look at current source theory. An ideal current source is able to supply unlimited voltage, which means the voltage across its. output is determined solely by the load resistance.
