Published on 06/27/2010

Activity Overview

Students explore the characteristics of capacitors. The activity begins with a look at the movement of charge in a parallel-plate capacitor and the effect of voltage on charge. Following the definition of capacitance, students explore how plate area, plate separation, and dielectrics affect capacitance. The activity ends with an investigation of the rate of discharge of a capacitor in an RC circuit.
