A thermistor is connected in series with a fixed resistor and a battery. The temperature of the thermistor increases. What happens to the potential difference across the fixed resistor?
It increases, because the current in the circuit increases
It increases, because the resistance of the thermistor increases
It decreases, because the current in the circuit decreases
It decreases, because the resistance of the thermistor decreases
