... Electric charge is quantized in units of the electron’s charge. Robert Millikan's oil-drop experiment (1908-13) demonstrated this fact directly, and measured the elementary charge. His experiment measured the force on tiny charged droplets of oil suspended against gravity between two metal electrode ...

... "If you put a current of electricity with no more push behind it than that up against the job of jumping the gap in a spark plug, it couldn't come near making the grade. So what has to be done is to take that low pressure current and use it to produce a current with a whole lot of pep. Sounds like t ...

History of electrochemistry
Electrochemistry, a branch of chemistry, went through several changes during its evolution from early principles related to magnets in the early 16th and 17th centuries, to complex theories involving conductivity, electric charge and mathematical methods. The term electrochemistry was used to describe electrical phenomena in the late 19th and 20th centuries. In recent decades, electrochemistry has become an area of current research, including research in batteries and fuel cells, preventing corrosion of metals, the use of electrochemical cells to remove refractory organics and similar contaminants in wastewater electrocoagulation and improving techniques in refining chemicals with electrolysis and electrophoresis.
