Thermistor circuit (4)

Consider the same circuit as in part 3 , where both switches are closed.

The (NTC) thermistor has a resistance $R_0 = 1875\Omega$ at $T_0 = 25^{\circ}\textrm{C}$ . Its resistance reduces to a fifth of its $25^{\circ}\textrm{C}$ resistance when the temperature is increased to $100^{\circ}\textrm{C}$ . Calculate, for a temperature of $60^{\circ}\textrm{C}$ , how much higher the voltage at node B is than at node A. ( $V_B - V_A)$

Convert your answer to $\textrm{mV}$ and round your answer to the nearest integer.

The thermistor is modelled by the Steinhart-Hart equation, where $B$ is a thermistor-dependent constant: $R(T) = R_0e^{B(\frac{1}{T}-\frac{1}{T_0})}$
