nodal analysis

The dual of the special case of mesh analysis is nodal analysis.

These are the nodes of nodal analysis.

Nodal analysis is possible when all the circuit elements' branch constitutive relations have an admittance representation.

A construct in Nodal analysis, a circuit analysis technique used in electrical engineering.

Kirchhoff's current law combined with Ohm's Law is used in nodal analysis.

Rank plays the same role in nodal analysis as nullity plays in mesh analysis.

Nodal analysis has limitations in representing inductors, floating voltage sources and the various forms of controlled sources.

Nodal analysis: The number of voltage variables, and hence simultaneous equations to solve, equals the number of nodes minus one.

Nodal analysis writes an equation at each electrical node, requiring that the branch currents incident at a node must sum to zero.

When elements do not have admittance representations, a more general extension of nodal analysis, modified nodal analysis, can be used.

It can be proved that such a DAE coming from the Modified Nodal Analysis will have differentiation index less or equal than two.

Because of the compact system of equations, many circuit simulation programs (e.g. SPICE) use nodal analysis as a basis.

SPICE1 was coded in FORTRAN and used nodal analysis to construct the circuit equations.

Nodal analysis produces a compact set of equations for the network, which can be solved by hand if small, or can be quickly solved using linear algebra by computer.

Modified nodal analysis was developed as a formalism to mitigate the difficulty of representing voltage-defined components in nodal analysis (e.g. voltage-controlled voltage sources).

The circuit equations resulting from the PEEC model are easily constructed using a modified loop analysis (MLA) or modified nodal analysis (MNA) formulation.

To increase the efficiency of the procedure, the circuit may be partitioned into its linear and nonlinear parts, since the linear part is readily described and calculated using nodal analysis directly in the frequency domain.

In analyzing a circuit using Kirchhoff's circuit laws, one can either do nodal analysis using Kirchhoff's current law (KCL) or mesh analysis using Kirchhoff's voltage law (KVL).

The BOEMRE currently uses the Merlin finite difference simulator and nodal analysis package to perform all WCD studies since using the software to determine the official flow rate for the Deepwater Horizon Oil Spill.

Unlike SPICE, which used Modified nodal analysis (MNA) to form the system of circuit equations, ASTAP instead used sparse tableau formulation (STA) to construct and solve a sparse matrix.

In electric circuits analysis, nodal analysis, node-voltage analysis, or the branch current method is a method of determining the voltage (potential difference) between "nodes" (points where elements or branches connect) in an electrical circuit in terms of the branch currents.

While simple examples of nodal analysis focus on linear elements, more complex nonlinear networks can also be solved with nodal analysis by using Newton's method to turn the nonlinear problem into a sequence of linear problems.

Such developments were based on the application of concepts and methods from graph theory, for example minimum spanning trees to depict individual tracks in a more rigorous way, clique analysis to identify standard tracks, and nodal analysis to determine the precise location of panbiogeographic nodes.

In Electrical Engineering Modified Nodal Analysis or MNA is an extension of nodal analysis which not only determines the circuit's node voltages (as in classical nodal analysis), but also some branch currents.
