A: There is only one source thermal
A resistance that doesn't change.
Changing the potential difference in a circuit does not change the resistance. Rather, it changes the current.
In a circuit, the primary types of sources (or "dutors") are voltage sources and current sources. Voltage sources provide a fixed voltage regardless of the current flowing through them, while current sources deliver a constant current regardless of the voltage across them. Both types can be ideal or real, with ideal sources having no internal resistance and real sources exhibiting some resistance.
It isn't. If you're using superposition, you open circuit current sources and short voltage sources; this is because the current source declares the current that will be flowing through that branch. Both current and voltage sources have a finite internal resistance.
You can modify the resistance of a thermistor by changing its temperature. As the temperature increases, the resistance of a thermistor decreases, and vice versa. By adjusting the surrounding temperature or applying heat or cooling, you can effectively change the resistance of the thermistor.
yes, calculate it from temperature coefficient of resistance.
You can change the resistance manually however there is no way to change the rate automatically.
