Question

A battery, capacitor, resistor, and switch are connected as shown. The capacitor is initially uncharged, and the switch is closed at t = 0 s. Recall that charges cannot flow across the gap between capacitor plates. At time t the charge on each plate of the capacitor is half of its final value. a. At time t, are the magnitudes of the potential differences across the capacitor and resistor zero or non-zero? Explain your reasoning. b. In the space below, draw and label separate free-body diagrams for a charge inside the battery and inside the resistor at time t c. Do any forces on your free-body diagrams above change with time? Describe which forces do, and how they change with time. d. Does the electric field in the capacitor change with time? If so, how does it change? e. Do charges ever stop flowing around this circuit? If so, what causes them to stop flowing? Explain.

Explanation / Answer

Yes at one time charges will stop flowing in the circuit. Initially the voltage across the capacitor is zero but as we closed the circuit charges will start accumulating across the plate of the capacitor. When the electric field is enough then there will be no flow of charges. The strength of the electric field will determine by the battery.
