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.
Answer Wiki. Practically, A source is modeled as an idea voltage source in series with a source resistance(due to the source components, connecting wires etc.). The terminal voltage measured at the source terminals will be less than the actual source voltage itself due to voltage drops in the series resistance. Rs needs to be considered whenever you do a practical design for the SCR as there is an upper limit to the amount of current the SCR can handle at the Gate Terminal given by Es/Rs.
