IR graphs Flashcards
1
Q
potential difference and current are directly proportional or inversely proportional to eachother?
A
directly proportional
2
Q
in fixed resistors and wires what are the current and PD like?
A
directly proportional
3
Q
what is the potential difference and current like in filament lamps?
A
not directly proportional because the temperature of the filament lamp increases as the resistance increases
4
Q
what is a diode?
A
a device that allows the current to travel in one direction only
