This document describes an experiment on charging and discharging of capacitors. It involves using a 100μF capacitor, 1MΩ resistor, 9V battery, and multimeter. The procedure is to connect these components in a circuit and take voltage readings across the capacitor at 20 second intervals as it charges.
For the equation of capacitor discharge, we put in the time constant, and then substitute x for Q, V or I: Where: is charge/pd/current at time t is charge/pd/current at start is capacitance and is the resistance When the time, t, is equal to the time constant the equation for charge becomes:
Because the current changes throughout charging, the rate of flow of charge will not be linear. At the start, the current will be at its highest but will gradually decrease to zero. The following graphs summarise capacitor charge. The potential difference and charge graphs look the same because they are proportional.
When a capacitor is discharged, the current will be highest at the start. This will gradually decrease until reaching 0, when the current reaches zero, the capacitor is fully discharged as there is no charge stored across it. The rate of decrease of the potential difference and the charge will again be proportional to the value of the current.
This process will be continued until the potential difference across the capacitor is equal to the potential difference across the battery. Because the current changes throughout charging, the rate of flow of charge will not be linear. At the start, the current will be at its highest but will gradually decrease to zero.
