currents equations, addressing every substitution and
simplification through six steps, ensuring that users
thoroughly understand the resolution methodology.
9) Numerical Results: The last section presents the
node voltages and branch currents which ultimately
solve the circuit under analysis. Currents are segmented
into three types: obtained by an existing current source
in the branch; computed through the Ohm's Law equation;
and obtained through the KCL equation (in case the
current belongs to a branch with one or more IVS). Each
current is provided with the expression (Ohm's Law or
KCL equation) and the respective result in order to clarify
users which equation was used to acquire such results.
IV. Conclusion
This paper addresses an educational web-based application
- U=RIsolve - which aims at introducing a didactic
component to existing circuit simulators, enabling
to explore innovative and more efficient teaching and
self-learning methodologies. U=RIsolve uses the QUCS
netlist file to simulate each circuit, providing users a
step-by-step analysis through the NVM. The app has already
been employed for conceiving new circuit analysis
exercises and as a complementary way of in-class
instruction. Moreover, we recently organised a handson
tutorial where students have used the application in
the scope of the preparation of one of their lab scripts.
THIRD QUARTER 2021
Ongoing work includes the design of a graphical user
interface module for drawing and modelling circuits to
make the application independent of third-party software
(QUCS in this specific instance). Additionally,
we intend to integrate other circuit analysis methods,
namely the Branch Current Method, the Mesh/Loop Current
Method and the Superposition Theorem, as well
as circuit simplification methods, e.g. based on the
Thévenin/Norton and Millman Theorems.
