Does voltage flow through a circuit or is it established across a circuit?

The 'charges' (electrons, in the case of a metal conductor) are ALREADY distributed within the conductor. They are in a state of constant, haphazard, movement at just short of the speed of light. When a potential difference is applied across the conductor, there is a tendency for these electrons to move from the negative potential towards the positive potential. This tendency is VERY slow; for example, an individual electron is unlikely to pass through the filament of a flashlight during the lifetime of its battery!

it established across the two points a circuits.
Voltage is a measurement of electrical pressure and not of flow and is constant until the circuit is broken by a open or reduced by a resistor. Current (amps) flowes through the circuit and is pushed by voltage. I suppose you could say that the voltage moves through the circuit after it is turned on until it is established everywhere but at the speed of light its not very long. Current is actually flowing through the circuit and is caused by free electrons being bumped from atom to atom through a conductor.

Answer
Let's start by getting rid of the misconception that voltage 'flows'. 'Voltage' is simply another word for 'potential difference'. Potential difference, as the name suggests, exists between different points in a circuit and the mechanical analogy is 'pressure'. Pressure doesn't 'flow'; neither does voltage.
So, voltage is, indeed, 'impressed across' a circuit.

What is the voltage drop running through the parallel potion of the circuit?
A: There is no voltage drop running through in a parallel circuit but rather the voltage drop across each branch of a parallel circuit is the same
The voltage measured directly across an open switch in a circuit will be?
The voltage measured across an open in a series circuit is the equivalent of the sourse voltage.
Normally a high current flows through a short circuit even if there is no change to the voltage. Why is this?
A high current flows through a short circuit even if there is no voltage change because the resistance across the short circuit is zero.
Is voltage established through a resistor or across a resistor?
Current = charge (electrons) flowing through a resistor.Voltage = energy lost across a resistor.Power = energy lost across a resistor per second.So yes you are correct. Current is established through a component, while voltage and power are established across a component.Answer'Voltage' is a synonym for 'potential difference'. As the name implies, voltage describes the difference in potential between (or 'across') two different points. So voltage is applied ACROSS a resistor.Further to the original answer. voltage is NOT equivalent to 'the energy lost across a resistor', and power is NOT 'established across a resistor' (power is simply a 'rate', nothing more)!
What is the voltage of a series circuit with four voltage drops of 30 volts?
there is 120V across the circuit.
Does voltage flow across a circuit or is it impressed across a circuit?
Voltage is impressed across a circuit. Current flows through a circuit.
What is the voltage drop running through the parallel potion of the circuit?
A: There is no voltage drop running through in a parallel circuit but rather the voltage drop across each branch of a parallel circuit is the same
What is an equation for power?
Power = (energy used)/(time to use it)Power dissipated by an electrical circuit =(voltage across the circuit) x (current through the circuit)or(resistance of the circuit) x (square of the current through the circuit)or(square of the voltage across the circuit)/(resistance of the circuit)
How is a parallel circuit the same as a series circuit?
In both cases, the power dissipated is measured by multiplying the voltage across the circuit by the current through the circuit.
Is a series circuit the same as a parallel circuit?
In both cases, the power dissipated is measured by multiplying the voltage across the circuit by the current through the circuit.
Normally a high current flows through a short circuit even if there is no change to the voltage. Why is this?
A high current flows through a short circuit even if there is no voltage change because the resistance across the short circuit is zero.
The voltage measured directly across an open switch in a circuit will be?
The voltage measured across an open in a series circuit is the equivalent of the sourse voltage.
Does voltage flow through a circuit or is voltage establish across a circuit?
voltage does not flow, current flowsAnswer'Voltage' is another word for 'potential difference' -you can think of it as being the equivalent of the difference in pressure across, say, the input and output ports of a central heating radiator which is responsible for pushing water to flow through that radiator. So 'voltage' exists across two points in a circuit, causing current to flow through the conductor between those two points.
What is voltage drop in an electrical circuit?
When a current flow on a conductor , or load or resistor, some voltage will drop across that load or resistor.AnswerA voltage drop is the potential difference appearing across individual components in a circuit, necessary to drive current through those components. The sum of the individual voltage drops around a series circuit will equal the supply voltage applied to that circuit.
What is the function of an amplifier in an electrical curcuit?
It essentially boosts the voltage across the amplifier, and through the circuit.
Why does higher resistance have a larger voltage drop across it?
In a d.c. circuit, voltage drop is the product of resistance and current through that resistance.
What will be the voltage in an inductance reactance circuit?
The voltage across the inductance alone will be(value of the inductance) times (the rate at which the current through it changes)
