【单选题】If the water temperature had increased after submerging resistor B, which of the following statements would have been most accurate?
A.
The fact that the water temperature increased after submerging Resistor B shows that resistor B is a thermistor.
B.
The fact that the water temperature increased after submerging Resistor B shows that resistor B is not an ohmic device.
C.
Since the measured current was the same when the initial water temperature was 23°C as when it was 25°C,resistor B is an ohmic device.
D.
Since the measured current was the same when the initial water temperature was 23°C as when it was 25°C,resistor B is not a thermistor.
