Charge and discharge voltage and current graphs for capacitors. Capacitor charge and discharge graphs are exponential curves. in the above circuit it would be able to store more charge. As a result, it would take longer to charge up to the supply voltage during charging and longer to lose all its charge when discharging.
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.
