Consider the circuit shown to the right. The light bulbs are identical and initially the capacitor is uncharged.
The switch is closed at time f = 0. Describe the behavior of bulb 1 and bulb 2 from just after the switch is closed to a long time later. Include your description a comparison of the brightness of the Explain your reasoning.
Bulb 1
Bulb 2
(b) Find the potential difference across the capacitor in terms of the voltage across the battery (Vbattery) 3 very long time after the switch is closed. Explain your reasoning.
(c) After the switch has been closed for a very long time, the switch is then reopened. Describe the behavior of bulb 1 and bulb 2 from just after the switch is opened to a long time later. Explain your reasoning.
