CAPE Physics Unit 2 · 2001 · Paper 2 · Question 1(b)(i)

A table of thermistor resistance values at various temperatures is given. The thermistor obeys R_T = R_0 e^(A/T), where R_T and R_0 are resistances at T K and 273 K, and A is a constant. A graph of ln(R_T) versus 1/T is plotted on page 5.

Use the graph on page 5 to calculate the value of the constant A.

This question uses a figure or table from the paper — you'll see it when you practise.
