The volt is the standard unit of electromotive force (EMF) or potential difference. An accumulation of static electric charge, such as an excess or shortage of electrons, is always, associated with a voltage. There are other situations in which voltages exist. Voltage is generated at a power plant, and produced in an electrochemical reaction, and caused by light falling on a special semiconductor [...]

Current can only flow if it gets a “push.” This might be caused by a buildup of static electric charges, as in the case of a lightning stroke. When the charge builds up, with positive polarity (shortage of electrons) in one place and negative polarity (excess of electrons) in another place, a powerful electromotive force exists. It is often abbreviated EMF.   Description of [...]

Whenever there is movement of charge carriers in a substance, there is an electric  current. Current is measured in terms of the number of electrons or holes passing a  single point in one second.  As far as Static Electricity is concerned so  Charge carriers, particularly electrons, can build up, or become deficient, on things without flowing anywhere. You’ve probably [...]
