Resistance And V= I X R Flashcards
1
Q
What does the graph look like for in a resistor
A
Current through a resistor is directly proportional to the potential difference
2
Q
What does the graph like in a filament light bulb
A
As the temperature increases the resistance increases this is why it is a curve
3
Q
What is the graphs like for a diode
A
Flat then curves up
The diode has a very high resistance in the other direction
4
Q
What do vi graphs shows
A
Resistance in a componenent
