Mastering the Node-Voltage Method

Flashcards covering key concepts and terminology from the Node-Voltage Method lecture.

Node-Voltage Method

A technique used to analyze circuits by determining the voltage at each node relative to a reference node.

Supernode

A supernode is formed when a voltage source is connected between two non-reference nodes.

Dependent Node

A node whose voltage is determined by a connected dependent source and does not require a KCL equation.

Voltage Source

A component that provides a specified potential difference between two points in a circuit.

Reference Node

A node in an electrical circuit that is defined as having zero voltage.

KCL (Kirchhoff's Current Law)

A principle stating that the total current entering a junction must equal the total current leaving the junction.

Independent Source

A source that provides a constant voltage or current regardless of other elements in the circuit.

Dependent Source

A source whose output depends on another parameter in the circuit, such as voltage or current.

Branch Current

The current flowing through a particular branch of a circuit, defined in terms of node voltages.

Constraint Equation

An equation that relates the dependent source to the node voltages in which it is involved.
