Use boundary
Choose the maximum decimal places shown. This does not increase source accuracy.
The capacitor is ideal; equivalent series resistance, dielectric loss, leakage, and ratings are excluded.
Use internally consistent units and retain extra precision when carrying the result into another calculation.
