Paschen's Law experiments

Paschen's Law describes how the electrical breakdown (sparking) between two electrodes in a gas depends on the gas pressure and the distance between the electrodes. The experiments involve gradually increasing voltage in a controlled gap, observing when a spark occurs. The law shows there's an optimal combination of pressure and distance where sparks are easiest to produce. This understanding helps in designing electrical systems in gases, such as antennas, vacuum systems, and gas-filled devices, by predicting when electrical discharge will happen under different conditions.
