Which statement fully describes the graph shown.
As current increases voltage decreases (inversely proportional). This graph does not follow Ohm's law, it is for a non-ohmic component.
As voltage increases current increases (directly proportional). This graph follows Ohm's law, it is for a non-ohmic component.
As voltage decreases current increases (inversely proportional). This graph does not follow Ohm's law, it is for an ohmic component.
As voltage increases current increases (directly proportional). This graph follows Ohm's law, it is for an ohmic component.
This graph is for a filament lamp. What is the reason for the shape of the line shown on the graph?
Filament lamps are variable resistors. So we can use a sliding scale to change their resistance, which will change the current going through them.
Filament lamps cool down when current runs through them, their resistance increases causing the current to decrease over time.
Filament lamps heat up as current runs through them, this increases resistance causing the current to decrease over time.
Filament lamps heat up as current runs through them, this increases resistance causing the current to increase over time.
