Capacitors store energy in the form of electric fields. We investigated this property in Exp 7 on Capacitors. However, on Exp 7 we used a DC voltage source and did not unplug anything. In this lab, we will charge a capacitor with a DC source and then unplug it, while investigating the rate of discharge. Additionally, we will investigate the rapid charging and discharging of an RC Circuit connected to an AC source.
