Charging a Capacitor: An RC circuit includes a basic switch. In position "a", the battery, resistor and capacitor are connected in series, and the capacitor charges. In position "b", the battery is replaced with a short, and the capacitor will discharge. Two voltmeters and an ammeter have been added to the circuit. A) The switch is moved to position "a", and the capacitor begins charging. At any given instant in the process, let "I" represent the current flowing through the ammeter, and let "q" represent the charge that has accumulated on the positively charged capacitor plate. Enter an expression for Kirchhoff's Loop Rule where the sum of the voltage changes totals zero.  B)Since the current is the rate of charge flow, substitute "dq/dt" for "I" in your expression from the previous step. With a little algebra, rearrange your expression so that all references to time appear on the left-hand side and all references to charge appear on the right-hand side. Input an expression for the…

In a series RC circuit, what will the graph of current versus time look like for the condition where the capacitor is initially uncharged at time=0 and then connected to a battery. Explain precisely; you do not need to include a graph.

An RC circuit includes a basic switch, two voltmeters and an ammeter. Initially the capacitor is either partially or fully charged, and the switch is open. Data collection begins, and then the switch is moved to position "b" allowing the capacitor to begin discharging.
