What sources of errors in capacitor in ac circuit experiment?

In an AC circuit experiment involving capacitors, sources of error can include measurement inaccuracies from instruments like multimeters or oscilloscopes, which may not provide precise readings at different frequencies. Additionally, parasitic elements such as equivalent series resistance (ESR) and equivalent series inductance (ESL) in capacitors can affect performance, leading to discrepancies between theoretical and experimental results. Furthermore, connection issues, such as loose or corroded contacts, can introduce resistance and impact circuit behavior. Environmental factors like temperature variations can also alter capacitance values and affect the experiment's outcome.
