voltage drop
voltage drop[′vōl·tij ‚dräp] (electricity) The voltage developed across a component or conductor by the flow of current through the resistance or impedance of that component or conductor. Voltage dropThe difference in voltage between the beginning and the end of a circuit, depending on the amount of resistance of the conductors. voltage dropThe difference in electromotive force between any two points in an electric circuit.voltage dropThe decline in voltage in an electrical circuit due to the resistance in the conducting line. This is why longer electrical runs in a building require thicker gauge wire and why AC power is transmitted over high-voltage lines. Higher current requires thicker and more expensive wires, but higher voltage does not. The high-voltage lines are reduced by transformers near the end of the line.
