Question text
36 A cell has a constant electromotive force and a constant internal resistance. A thermistor is connected between the terminals of the cell. The temperature of the thermistor is increased. Which statement about the change of the cell’s terminal potential difference (p.d.) is correct? A The terminal p.d. is decreased because more work is done moving unit charge through the internal resistance of the cell. B The terminal p.d. is decreased because the current in the thermistor is decreased. C The terminal p.d. is increased because more work is done moving unit charge through the thermistor. D The terminal p.d. is increased because the current in the thermistor is increased.
36 A cell has a constant electromotive force and a constant internal resistance.
A thermistor is connected between the terminals of the cell.
The temperature of the thermistor is increased.
Which statement about the change of the cell’s terminal potential difference (p.d.) is correct?
A The terminal p.d. is decreased because more work is done moving unit charge through the
internal resistance of the cell.
B The terminal p.d. is decreased because the current in the thermistor is decreased.
C The terminal p.d. is increased because more work is done moving unit charge through the
thermistor.
D The terminal p.d. is increased because the current in the thermistor is increased.
