Charging and Discharging a Capacitor

Charging a capacitor isn''t much more difficult than discharging and the same principles still apply. The circuit consists of two batteries, a light bulb, and a capacitor. Essentially, the electron current from the batteries will continue to run until the circuit reaches equilibrium (the capacitor is "full"). Just like when discharging, the bulb starts out bright while the electron
