What type of conductor is a filament lamp?

Non-ohmic conductor

What shape is the current-voltage graph for a filament lamp?

Curved line

How must the ammeter be connected in this circuit?

In series with the bulb

How must the voltmeter be connected in this circuit?

In parallel with the bulb

What is the purpose of the variable resistor (rheostat) in this experiment?

To control voltage and current

On the I-V graph, which variable should be plotted on the y-axis?

Current (I)

At low voltages, what happens to the filament lamp's resistance?

It is relatively low

What happens to the filament's resistance as voltage increases?

It increases due to heating

Why does the tungsten filament's resistance increase at higher temperatures?

Atoms vibrate more, impeding electrons

Why does the I-V curve flatten at higher voltages?

Higher resistance limits current rise

What happens if you connect the ammeter in parallel with the bulb?

Creates a short circuit

Using the formula R=VIR = \frac{V}{I}, what can you calculate at any point on the graph?

Resistance at that operating point
