Build the circuit yourself: place the equipment on the bench and wire it up, including the voltmeter across the component under test.
Build the circuit yourself: a power supply, ammeter, variable resistor and switch in series with the component under test, and a voltmeter connected across the component. Drag equipment onto the bench and arrange it however you like. Drag from the small dots on each instrument to wire up the circuit yourself, including the voltmeter. Everything here also works by clicking: pick an item, then tap it again to place it; tap one terminal, then another, to wire them.
An ohmic conductor at constant temperature — current is directly proportional to voltage.
Close the switch before taking a reading.
No readings yet. Close the switch, set a test voltage — try both positive and negative — and press Record reading.
Record at least three readings for each component — resistor, filament lamp and diode — to compare their graphs here.
