Conclusion #1
The bulb does not obey the Ohm's law. We can see that the line in the graph is is curved, so the gradient (current) changes and is not proportional to the IV. This is because the change of temperature affects the resistance. When heat is applied, the positive ions gain more KE and vibrates, making it harder for the electrons to travel through the circuit.

What is resistance?
Resistance opposes currents and is measured by ohms.

What is Ohms Law?
The potential difference is proportional to the current through it. The constant of proportionality is called the "resistance", R. Ohm's Law is given by: V = I R where V is the potential difference between two points which include a resistance R.

Ohmic
- Straight line/ linear line
- Constant variables
- IV is proportional
- Obey Ohms Law

Non-Ohmic
- Curved line
- Non-constant/Changing variable
- Not proportional
- Don't obey Ohms Law
