Dc Circuits. A circuit is a closed loop through which electrons can flow. A direct current (DC) circuit is a type of circuit with direct current (as opposed to alternating current) flowing through it. That is, in a DC circuit, the current flows in one direction.
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.
