Charging And Discharging A Capacitor

Charging And Discharging A Capacitor

Examine how electrons flow within a circuit consisting of a capacitor and battery using this tutorial. Visitors can throw a virtual switch to connect the circuit and observe the battery charge the capacitor. Once the capacitor is fully charged, the switch can be reversed to discharge the capacitor.

Nice graphics, very easy to use, but nothing quantitative to learn. The flow of charges during
discharge is misleading. I would like to see 1) a resistance in series with the
capacitor, and 2) a display of V and/or I vs. time.
Used in course? Yes

Outstanding! This simulation shows the user how charge flows in a circuit
containing a capacitor. The user then understands why the capacitor charges,
and why it discharges once the EMF is removed. Very nice graphics and smooth
