Ohmic conductor
Voltage is directly proportional to current because it's straight and goes from 0 to 0.
1 of 8
Filament Lamp
As voltage increase current increase. NOT an ohmic conductor because the resistance is changing because it's getting hot.
2 of 8
Diode
As voltage increases, current increases.
3 of 8
Thermistor
As voltage increases, current increases but increases more rapidly throughout. NOT an ohmic conductor.
4 of 8
Direct current (DC)
Current which always passes in the same direction.
5 of 8
Alternating current (AC)
Current which is constantly changing direction.
6 of 8
UK Mains supply
230 Volts.
