SUMMARY
The leakage resistance of a capacitor can be calculated using the formula Rl = ρ * Er * Eo / C. For a capacitor with a capacitance of 100pF, relative permittivity of 12, and resistivity of 10^14 ohm-meters, the calculated leakage resistance is approximately 1076.87 ohms. This value, while significant, reflects the ideal behavior of a capacitor, which theoretically has infinite leakage resistance. The calculations confirm that the leakage resistance can be substantial, but practical measurements may not capture such high values.
