The interpretation of the graphs associated with capacitor charge and discharge is pivotal in understanding the concepts of capacitance. The gradient of the Q vs. Time graph at any point gives the instantaneous current in the circuit. The area under the V vs. Time graph represents the total energy stored in the capacitor.
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.

Understanding the graphical representation of capacitor charging and discharging is crucial for comprehending the underlying physics. The voltage across the capacitor increases logarithmically over time as it charges. The charge on the capacitor, represented by Q, follows a similar pattern, increasing as the capacitor stores more energy.
Discharge Equation: Q = Q0 * e(-t/RC), where Q0 is the initial charge. Charging Equation: Q = Q0 * (1 − e(-t/RC)). These equations are fundamental for calculating the charge on the capacitor at any given time during the charging or discharging process. Practical investigations into capacitor dynamics are integral for a comprehensive understanding.
