The voltammeter works by electrolysis: using electricity to break a compound down into elements. The electric current is passed through a known amount of a compound for a set amount of time. The stronger the current the faster the reaction so, by measuring the remaining compound and the elements, you can determine how much electricity is used. Before this he detected electricity by touching the ends of a circuit to a frog to see if its legs twitched.
Faraday lived and worked at the Ri for over 50 years and in that time he invented the first electric motor, generator and transformer.
