Item 5A large capacitor has a charge + q on one plate and -q on the other. Attime t = 0, the capacitor is connected in series to two ammeters and a lightbulb. Immediately after the circuit is closed, the ammeter connected to thepositive plate of the capacitor reads Ip and the ammeter connected to thenegative plate of the capacitor reads IN (Figure 1)Each ammeter reads positive if current flows through the circuit in aclockwise direction (from the + to the terminal of the meter).Figure+ g(t)+|||q(t)AIN1 of 1CorrectThis is a fundamental result that reflects the law of conservation of charge. In a circuit where all elements are arranged in series, the current is the same through all theelements. Otherwise, the electric charge would, in effect, "accumulate" or "disappear" somewhere in the circuit.Part CIn a circuit where all elements are arranged in parallel, the current may be different in different branches. This result is formalized in Kirchhoff's junction law: The algebraicsum of currents entering any junction must be zero.What is the relationship between the current and charge? As the charge q (t) on the positive plate of the capacitor decreases, what happens to the value of the current?The currentSubmitCorrectPart Dtbright =increases.Submitdecreases.does not change.Previous AnswersProvide FeedbackLight bulbs are often assumed to obey Ohm's law. However, this is not really true because their resistance increases substantially as the filament heats up in its "working" state.A typical flashlight bulb at full brilliance draws a current of approximately 0.5 A when connected to a 3-V voltage source. For this problem, assume that the changing resistancecauses the current to be 0.5 A for any voltage between 2 and 3 V.Suppose this flashlight bulb is attached to a capacitor as shown in the circuit from the problem introduction. If the capacitor has a capacitance of 3 F (an unusually large but notunrealistic value) and is initially charged to 3 V, how long will it take for the voltage across the flashlight bulb to drop to 2 V (where the bulb will be orange and dim)?
