To make sure the capacitor is fully charged, you wait another 45 seconds. Now you remove the battery from the circuit, and connect the capacitor to the lightbulb. The diagrams below show the electron current in the circuit at three different times (0.01 s, 8 s, and 240 s) after the connection to the bulb is made. Which diagram best represents the state of the circuit at a time 0.01 second after connecting the wires? a b c 2. 3/3 points Question: MI3 20.1.X.032.alt02 When a particular capacitor, which is initially uncharged, is connected to a battery and a small light...
