When a particular capacitor, which is initially uncharged, is connected to a battery and a small light bulb, the light bulb is


initially bright but gradually gets dimmer, and after 45 seconds it goes out. The diagrams in Figure 20.62 show the electric


field in the circuit and the surface charge distribution on the wires at three different times (0.01 s, 2 s, and 240 s) after the


connection to the bulb is made. The diagrams in Figure 20.62 show the pattern of electric field in the wires and charge on


the surface of the wires at three different times (0.01 s, 8 s, and 240 s) after the connection to the battery is made. Which of


the diagrams best represents the state of the circuit at each time specified?


(a) 0.01 s after the connection is made


(b) 8 s after the connection is made


(c) 240 s after the connection is made
