When the thermistor is placed in a warm environment it has a resistance of \(100 \Omega\). We can calculate the voltage across the thermistor under these conditions. First find the total ...

The voltage across ... gives rise to the equation \(E= {V_{tpd}} + {V_L}\) This equation can be written in different forms, eg \(E= I(R + r)\). To solve problems on internal resistance it should ...
