# Potential Difference Graphs

HideShow resource information
The current through a resistor at constant temperature is...
directionally proportional to p.d.
1 of 7
Different resistors have different resistances and that is why there can be...
different slopes
2 of 7
For a bulb, the current flowing through it increases as...
the p.d. across it increases
3 of 7
At higher p.d.s, the current increases less because...
the resistance of the bulb is greater when the current is higher (due to temp increase)
4 of 7
So the graph looks like a...
stretched out s
5 of 7
A diode will not conduct unless the p.d. across it is a...
certain value (usually 0.6 V)
6 of 7
The diode will not allow reverse currents to...
flow through it
7 of 7
