The model's fit to the data may not be perfect due to several factors. One potential source of discrepancy is the assumption of ideal conditions when deriving the parallel plate capacitance formula $(C=K{}_0\frac{A}{d})$ from Gauss' Law. This derivation assumes perfectly parallel plates with uniform electric field, neglecting edge effects and fringing fields. Realworld conditions, such as plate imperfections or the influence of nearby objects, may contribute to deviations between the model and experimental data. Additionally, factors like static discharge and humidity could impact the accuracy of measurements, leading to discrepancies between the model and observed results.
