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 ...

Basically when the device is turned on, the thermistor is still relatively cool and so acts as a high resistance, limiting the current. Over time, as more current flows through the thermistor ...

An example is a filament lamp. As current increases, the filament gets hotter and the resistance of the bulb increases. A thermistor is a device that’s resistance changes with temperature.
