FAQ
What does the “Series & parallel I–V rules” lab practice?
Tune parameters and match readouts to the “Series & parallel I–V rules” relations — useful for prep and demos.
How do I connect meters?
Ammeter in series; voltmeter in parallel — watch polarity and range.
When does Ohm’s law apply?
For ohmic conductors I=U/R; nonlinear devices need their own curves.
Series vs parallel current and voltage?
Series: same I, voltages add. Parallel: same U, branch currents add.
