Figure P19.42 shows a circuit containing a battery in series with a resistor and a lightbulb. The brightness of the lightbulb depends on the current through the bulb: increasing the current increases the brightness, while decreasing the current reduces the brightness. How could you connect another resistor to this circuit so as to increase the brightness of the bulb? That is, would you connect the new resistor to points A and B, A and C, or B and C?
