Document Summary
An ideal conductor is represented by unbroken lines between other circuit elements. The voltage between the ends of an ideal conductor is zero regardless of the current flowing in it. In other words, the resistance of an ideal conductor is zero. Points in a circuit that are connected by ideal conductors can be considered as a single point. An ideal conductor is also called a short circuit. If there are no conductors or other elements between two parts of a circuit, we say that an open circuit exists between these two parts of the circuit. Current flowing through an open circuit is always zero (the resistance of an open circuit is infinite) An ideal independent voltage source maintains a specified voltage across its terminals. The voltage across such a source does not depend on current flowing through the source or other elements in the circuit. The definition of an ideal voltage source is somehow contradictory.
