Electrical charging associated historically with rubbing materials. It supplies ordinary electric charge, not a separate electrical substance. Compared with a chemical source, a friction machine can have a very different voltage, charge delivery and internal impedance.
In 1833 Michael Faraday compared electrical effects from different sources and then their quantitative delivery. His galvanometer test discharged a machine-charged jar battery through a wet thread and the detector, connecting frictionally produced charge to magnetic action.[ref]
