Voltage's commonly used as a short name for electrical potential difference. In this introduction, the term "voltage"'s however used to mean electric potential, for example a specific value (not a difference), and's denoted by the symbol V. The SI unit for voltage's the volt (symbol: V). Note that International Standards maintain this distinction between "sloping vee" (V) and "upright vee" (V). The voltage difference between two (electron) positions "A" and "B", inside a solid electrical conduc… (More on Voltage)
