  2. Kirchhoff's circuit laws - Wikipedia

    en.wikipedia.org/wiki/Kirchhoff's_circuit_laws

    A matrix version of Kirchhoff's current law is the basis of most circuit simulation software, such as SPICE. The current law is used with Ohm's law to perform nodal analysis. The current law is applicable to any lumped network irrespective of the nature of the network; whether unilateral or bilateral, active or passive, linear or non-linear.

  3. Nodal analysis - Wikipedia

    en.wikipedia.org/wiki/Nodal_analysis

    Kirchhoff's current law is the basis of nodal analysis. 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.

  4. Kirchhoff's laws - Wikipedia

    en.wikipedia.org/wiki/Kirchhoff's_laws

    Kirchhoff's laws, named after Gustav Kirchhoff, may refer to: Kirchhoff's circuit laws in electrical engineering; Kirchhoff's law of thermal radiation; Kirchhoff equations in fluid dynamics; Kirchhoff's three laws of spectroscopy; Kirchhoff's law of thermochemistry; Kirchhoff's theorem about the number of spanning trees in a graph

  5. Mesh analysis - Wikipedia

    en.wikipedia.org/wiki/Mesh_analysis

    Mesh analysis and loop analysis both make systematic use of Kirchhoff’s voltage law to arrive at a set of equations guaranteed to be solvable if the circuit has a solution. [1] Mesh analysis is usually easier to use when the circuit is planar, compared to loop analysis.

  7. Harmonic balance - Wikipedia

    en.wikipedia.org/wiki/Harmonic_balance

    The name "harmonic balance" is descriptive of the method, which starts with Kirchhoff's Current Law written in the frequency domain and a chosen number of harmonics. A sinusoidal signal applied to a nonlinear component in a system will generate harmonics of the fundamental frequency. Effectively the method assumes a linear combination of ...

    Remember that guidelines are not set in stone — rather, they're good rules to follow. For instance, if you’re 30 years old and earn $75,000, you should try to have that much saved in your 401(k).

  9. Pipe network analysis - Wikipedia

    en.wikipedia.org/wiki/Pipe_network_analysis

    To satisfy the Kirchhoff's second laws (2), we should end up with 0 about each loop at the steady-state solution. If the actual sum of our head loss is not equal to 0, then we will adjust all the flows in the loop by an amount given by the following formula, where a positive adjustment is in the clockwise direction.
