DC Linear Circuits 3.35
DC Linear Circuits (DCLC 3.30) is a program designed for calculating complex DC electrical circuits. DC Linear Circuits supports three methods for calculating electrical circuits: 1) the Kirchhoff's Law Method (KLM), 2) the Loop Current Method (LCM), and 3) the Nodal Potential Method (NPM). For a single-loop electrical circuit, the calculation is performed using Ohm's Law. The program provides a detailed (step-by-step) solution with a report in MS Word format.

  • DCLC versions

    The demo version of the program is free but has the following functional limitations:
    1. Full calculation is available for electrical circuits where N ≤ 5 (where N = number of loops + number of voltage/current sources).
    2. Partial calculation is performed for circuits where N > 5.
    The licensed version performs full calculations for all electrical circuits with no limits on the number of elements. The only restriction is the size of the drawing area.
    To use the licensed version, you must purchase an activation code (license key). The activation code is valid for two months. The licensed version requires an internet connection to verify the current date, as the activation code is time-limited.


  • Benefits of DCLC

    • DCLC is a training program that will allow you to easily master the basic methods of calculating complex electrical circuits.
    • DCLC generates two types of reports: 1) within the text window below the workspace, and 2) in MS Word format.
    • DCLC formats systems of equations in a standardized way: both in symbolic and numerical forms.
    • DCLC solves systems of equations using the inverse matrix method, explaining the process of forming the main matrix, deriving the inverse, and providing the final solution.
    • DCLC creates reports in .docx format, compatible with popular editors such as MS Word, OpenOffice Writer, WPS Writer, and Google Docs.
    • DCLC saves you time when formatting and preparing technical documentation.
    • DCLC helps students prepare for coursework defense, tests, or exams in electrical engineering.

  • DCLC System Requirements

    The DCLC software is designed for Windows OS. Step-by-step calculations are displayed via the built-in text block and Microsoft Word. Below are the supported versions of Windows and MS Word.
