ET331 · Electrical Network Analysis

Experimental Platform for the Analysis of Electrical Networks

A course package for building real resistor networks on a freely configurable connector panel - with integrated current and voltage sources - and verifying the classical theorems of circuit analysis by measurement.

Experiments

Kirchhoff's current and voltage laws applied to resistor networks
The superposition theorem for networks with multiple sources
Thévenin and Norton equivalent circuits and their equivalence
Millman's theorem for parallel sources
Star–delta transformation
The mesh-current and node-voltage analysis methods
Power matching between source and load

Description

The platform turns the classical theorems of circuit analysis into physical experiments. The experiment card is a freely configurable connector panel on which students build real resistor networks - from simple series and parallel combinations to multi-loop networks with several sources. Two constant-current sources and two constant-voltage sources are integrated directly on the card, and a set of 18 plug-in resistors provides the network elements. Every theorem in the DC circuit-analysis curriculum is then verified by measurement: currents and voltages are acquired by the ET300 base system's virtual instruments and compared against the calculated predictions.

Courseware

The interactive multimedia course - at least 5 hours of directed instruction - works through Kirchhoff's laws, superposition, Thévenin, Norton and Millman equivalents, star–delta transformation, the mesh-current and node-voltage methods, and power matching, each with a guided experiment on the card. Exercises are evaluated automatically, with Romanian-language support throughout.
