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 ...

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 ...

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.

Some years ago, we paid a couple of dollars for an electronic component called a thermistor, whose only job is to vary resistance as temperature changes.
