Current–potential difference characteristics
Put a resistor, a filament lamp and a diode in turn into a circuit with a reversing switch, read the ammeter and voltmeter in both directions, and compare the three I–V graphs.
This simulation supports preparation and data-analysis practice. It does not replace carrying out real practical work.
