EE 2120 Chapter : 6 IntroductionToCircuitElements
Document Summary
An electrical source is a device that is capable of converting non-electric energy to electric energy and vice versa. Electrical sources can deliver (supply) or absorb power. Md ebrahim s, electrical circuits, http://www. engineersblogsite. com/define-active-and-passive- circuit-elements. html, 2013. Many practical systems can be modeled with using sources and resistors. The analytical techniques for solving circuits with inductors and capacitors are the same as those for resistive circuits. Voltage between ends of an ideal conductor is zero. Maintains a constant voltage across its terminals regardless of the current flowing in those terminals. The voltage is known, but current is determined by the circuit to which the source is connected. The voltage can be either independent or dependent on a voltage or current elsewhere in the circuit and be constant or time-varying. Circuit symbol: maintains specified voltage between its terminals regardless of the current through those terminals, two-terminal element (or device)
