Identify the component represented in this graph? Two answers are correct:
Filament Bulb
Ohmic Conductor
Variable Resister
Fixed Resistor
For a fixed resistor, the potential difference is ..................... .................... to the current
(a)
Identify the component represented by this graph:

Explain your answer to the previous Q.
Use a description of the graph to support your answer (2 marks)
Explain how temperature affects resistance (2 marks)
Using your understanding of temperature and resistance, why does the Current/P.d Graph for a filament bulb look like this? Use the graph to support your answer (3 marks)
A diode (or semiconductor) only allows current to flow ............... ....................
This explains why the graph has a flat line before alternating the current flowing through the diode.
(a)
