Chapter 7 Direct Current Circuits web.mit.edu

In the last Chapter, we have shown that electrical energy must be supplied to maintain a constant current in a closed circuit. The source of energy is commonly referred to as the electromotive force, or emf (symbol). Batteries, solar cells and thermocouples are some examples of emf source.

Lessons In Electric Circuits Volume I (DC) Chapter 1

An open circuit is one where the continuity has been broken by an interruption in the path for electrons to flow. A closed circuit is one that is complete, with good continuity throughout. A device designed to open or close a circuit under controlled conditions is called a switch. The terms quot;openquot; and quot;closedquot; refer to switches as well as entire circuits. An open switch is one without continuity electrons cannot flow
