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.
A capacitor acts as an open circuit after long time period, and acts as a short (or voltage source) for short time periods, given a change in voltage level. The inductor acts as a short circuit after a long time period, and acts as an open circuit (or a current source) for a short time period given a change in voltage level. The actual current that flows however is based on the initial conditions, BOTH current AND voltage.
