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 battery or generator produces voltage -- the force that drives current through the circuit. Take the simple case of an electric light. Two wires connect to the light. For electrons to do their job in producing light, there must be a complete circuit so they can flow through the light bulb and then back out.our blood vessels, arteries, veins and capillaries are like the wires in a circuit. The blood vessels carry the flow of blood through your body. The wires in a circuit carry the electric current to various parts of an electrical or electronic system.
