For other uses, see Volt (disambiguation). The volt (symbol: V) is the derived unit for electric potential, electric potential difference (voltage), and electromotive force.
VDC is an abbreviation fot volts DC.. DC stands for direct current, which means the voltage is constant (as opposed to AC, alternating current, in which the voltage is constantly oscillating between positive and negative polarity). And a note about the term direct current: don't think too much about what the words actually mean.
