The decrease in voltage from the beginning of a circuit to the end of a circuit due to resistance.

Loss of voltage due to length of run or resistance.

A partial loss of electrical power due to the resistance of the cable to the flow of electricity. Voltage drop usually is indicated by dim lights at the end of long wire runs.

The amount of voltage across a resistor in an electrical circuit.

A reduction in voltage level caused by a current flowing through an impedance; equal to the current impedance product.

A reduction in voltage in conductors caused by current flowing through its resistance. It is equal to the product of current times feeder resistance.

The difference in voltage between two points. It is the result of the loss of electrical pressure as a current flows through a resistance.

A reduction of voltage in an electrical circuit.

The net difference in the electrical potential (volts) when measured across a resistance or impedance (ohms). Its relationship with current is described in Ohm's Law.

The difference in potential between two points caused by a current through an impedance or resistance.

a decrease in voltage along a conductor through which current is flowing

The electrical potential (voltage) that exists across two points of an electrical circuit.

Voltage value as measured across each resistor or load.

Reduction in applied voltage due to current flow through a circuit or a portion of the circuit (current x resistance).

The voltage developed between the terminals of a circuit component by the flow of current through the resistance or impedance of that part.

The loss of voltage in an electric conductor between supply tap and load tap.

The voltage lost along a length of wire or conductor due to resistance. The voltage drop is calculated using Ohm's Law. Voltage drop is also measured for resistors.

units = Volts (DC) or Volts RMS (AC). Sometimes referred to as Saturation Voltage. In any solid state control that switches a load, there will be some voltage dropped across the output. This voltage drop or saturation voltage will often vary with the amount of current going through the output section and the load. It should be specified with current conditions.

The voltage developed across a component of conductor by the current flow through the resistance or impedance of the component or conductor.

The change in potential between two points in a circuit caused by a current flow through components within a circuit.

Loss of voltage (electrical pressure) caused by the resistance in wire and electrical devices. Proper wire sizing will minimize voltage drop, particularly over long distances. Voltage drop is determined by 4 factors: wire size, current (amps), voltage, and length of wire. It is determined by a consulting wire sizing chart or formula available in various reference tests. It is expressed as a percentage. Water analogy: Friction Loss in pipe.

The voltage developed across a component or conductor by the flow of current through the resistance or impedance of that component or conductor.

Loss of electrical current on long wiring runs

Voltage or difference in potential developed across a component due to current flow.

The difference in potential measured between two points caused by resistance or impedance.

That portion of the voltage used or "consumed" by each device in a circuit.

The loss of voltage in a circuit caused by resistance.

A change in available voltage between two points in a circuit, due to current flowing through resistance. Also known as an IR drop.

This is the difference in current along a circuit caused by the resistance of the lights and the wire. When using low voltage wiring it can cause lights at the far end from the transformer to be noticeably dimmer than the ones nearer.

When using 12 volts, the cable needs to be matched to the load and distance, otherwise there may be less than 12 volts at the end of the cable run. This does not cause damage to the luminaire, but if the voltage drop is considerable, then the light produced will have a yellowing effect and may also be dim.

The amount of energy used by a device that has resistance in a circuit.

Should current flow through a resistor inside a closed electric circuit, a voltage drop will occur.

The loss of voltage between two points due to the internal impedance or resistance of the interconnections.

Voltage drop is the reduction in voltage in an electrical circuit between the source and utilitization device. Voltage drop, which is present in all electrical circuits powering any device, must be considered to varying degrees in circuit design. In electrical wiring national and local electrical codes may set guidelines for maximum voltage drop allowed in a circuit, to ensure reasonable efficiency of distribution and proper operation of electrical equipment.
