Series & parallel circuits
Series: same I, voltages add, R=ΣRₖ. Parallel: same U, currents add, 1/R=Σ1/Rₖ; voltage/current division rules.
DC circuitsInstrument reading, resistivity, Ohm’s law, EMF, RC.

FAQ
What does MVP mean on this page?
An interactive sketch with formulas and parameters. Polished Ready labs are the full bench experience.
What does the “Series & parallel circuits” lab practice?
Tune parameters and match readouts to the “Series & parallel circuits” 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.
