C.3.1—Translating between data forms question 1
A student investigated the behaviour of a thermistor using the circuit shown in the diagram.
She heated the thermistor to 100 °C and measured the potential difference V across it. She decreased the temperature θ and recorded further measurements of V and θ until the temperature reached 10 °C.
The student plotted a graph of her measurements of V and θ.
Estimate the value of V for a temperature of 0 °C.
