Draw a schematic of the circuit.
The student takes the room temperature measurement and notes it. The result is displayed in Fig. 2.2. Record the reading $V_W$ from Fig. 2.3.
The thermistor is put into the beaker of ice and water and, after a minute, the voltmeter is read once more. Record the reading $V_C$ from Fig. 2.5.
Calculate the average change in voltage for one degree temperature change $\Delta V_{AV}$ using the equation: $\Delta V_{AV} = \dfrac{V_C - V_W}{T_W - T_C}$. State the unit of your answer.
Use your answer to (d)(i) to predict the voltage $V_{PB}$ across the thermistor when it is at body temperature. Body temperature is $37^{\circ}\text{C}$. You may assume that the average change in voltage for one degree temperature change $\Delta V_{AV}$ remains constant.
State whether the student's results show that $V_{PB}$ and $V_{AB}$ are equal within the limits of experimental accuracy. Support your response with a calculation.
