⚡ High-Voltage Test Electrodes: Field, Capacitance, Energy and Force (2D cross-section)

Cross-section of a pair of high-voltage test electrodes modelled as parallel plates. Set voltage, gap, area and a dielectric fill, and watch field strength, capacitance, stored energy, plate attraction and the margin to air breakdown. Same equations, defaults and ranges as the 3D page, with four in-page numerical checks.
