What is the difference between potential difference and current?
think of potential as pressure and current as flow. you can have pressure in a water hose with out flow. open the valve and current happens. The difference in potential divided by the impedance is equal the current.
Does voltage forces electrical energy though a circuit?
You could say yes. The usual analogy is the height of a water fall relative to the flow of the water in a stream. If the potential difference is great it is similar to a high fall since the height difference is what drives the water down the falls.
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!
What is A Resistor In A conductor?
Resistors and conductors are actually two sides of the same story. They both conduct electricity and they both resist conducting electricity. The difference is how well they conduct electricity. Copper, Silver and Aluminum are examples of brilliant conductors. They resist very little. Coal-fibers and various metal oxides are examples of poor conductors. They resist much more and falls into the category of being a resistor. The comparison can easily be made with a water pipe-line. A huge dimension can carry a lot of water (This is electrical current). It can also contain high pressure (In this analogy, that would be Voltage) A very small dimension can not carry much water at all (The current is limited. This is what physically happens in a resistor.) The water pressure is the same, then the big pipe might fill a bathtub in 30 seconds where as the small pipe would maybe need 10 minutes or more. It works "exactly" the same way with electric components as conductors and resistors. Some people claim that a conductor is the opposite of a resistor. This is a wrongful interpretation although it seems to make sense... They are both conductors of voltage (water pressure as an analogy). A resistor only limits the current, Amount of water in previous analogy, somewhat, this depending on the specifications of the resistor. A conductor is a good leader of the electricity and a resistor is damping the electricity.

Is electric current and current the same thing?
Not really. You can compare them with the analogy of water flowing through a pipe. For water to flow, there must be a pressure difference across the ends of the pipe. An electric current is a movement of electric charges along a conductor. For those charges to move, there must be a voltage (more accurately, a 'potential difference') across the ends of the conductor. So a potential difference is required to cause current to flow.
What is the difference between potential difference and current?
think of potential as pressure and current as flow. you can have pressure in a water hose with out flow. open the valve and current happens. The difference in potential divided by the impedance is equal the current.
What is the purpose of analogy?
The purpose of analogy is to explain or clarify. When you make an analogy, you make comparisons between two things.

What causes potential difference?
A potential difference causes an electric current. Think of it like a river : the source of water is the most elevated point of the river, so the water has a lot of gravitational potential energy. The end of the river is the lowest point of it, so the water has very low gravitational potential energy. What happens between these two points? Water flows! This analogy can be applied to electricity; the potential difference is caused, for example, by a battery in an electric circuit.
Can you write a sentence with the word analogy in it?
An analogy can be helpful in explaining complex concepts by drawing parallels between two different ideas or situations.
Does voltage forces electrical energy though a circuit?
You could say yes. The usual analogy is the height of a water fall relative to the flow of the water in a stream. If the potential difference is great it is similar to a high fall since the height difference is what drives the water down the falls.
