hideously important voltage current graphs Flashcards
1
Q
metal filament lamp:
A
as the temperature of the metal filament lamp increases, the resistance increases
2
Q
wire:
A
the current through a wire (at a constant temperature) is proportional to voltage
3
Q
diode:
A
current will flow through a diode in one direction
4
Q
different resistors:
A
the current through a resistor (at a constant temperature) is proportional to the voltage. different resistors have different resistances. that will be evident on the graph.
