Volt (or Volts): Unit of measure for electromotive force (EMF), the electrical potential between two points. An electrical potential of 1 volt will push 1 ampere of current through a 1-ohm resistive load.
Using a common plumbing analogy, voltage is similar to water pressure and current is analogous to flow (e.g. liters per minute).
In equations, the symbol E is often used (as in: E = IR). V is the symbol for the unit of measure, Volt.
