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.
Vcc = Collector supply voltage, Vee = Emitter supply, Vbb= Base supply voltage, Vdd = Drain supply, Vss = source supply. Since there is no notion to identify ground (0) this method was simply adopted. The voltages can be negative or positive depending on the the device and the circuit configuration.
