Transcribed Image Text:An observational experiment is conducted in
which the current through a lightbulb
connected to a variable power source is
measured as the potential difference of the
power source is changed, resulting in the
following graph:
Current (A)
Potential Difference (V)
Transcribed Image Text:Which of the following explanations is
consistent with the results of this experiment?
The lightbulb does not follow Ohm's Law
Δυ
(the equation R = 4º does not apply to
the lightbulb).
I
The resistance of the lightbulb increases
as a higher potential difference is
applied to it.
The resistance of the lightbulb
decreases as a higher potential
difference is applied to it.
O The resistance of the lightbulb increases
over time as it is used.
The resistance of the lightbulb
decreases over time as it is used.
