Electric chargeMillikan oil-drop experiment

Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

Droplet charges clustered at integer multiples of a common unit.

How to interpret this relation type

The source theory, law, entity, prediction, or structural claim is directly tested, supported, constrained, or established by the target experiment or observation. Experimental support is not final logical proof; the edge detail states exactly what was measured.

Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

Combined with charge-to-mass measurements, the oil-drop result fixed the electron’s charge and mass scale.
