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.
This is a weird comparison but role with me here. Imagine a lazy river with beach balls in it. The river essentially is the potential, also known as the voltage. It acts as sort of the pushing force to the beach balls which is the current. Current by definition is charge per second so how much charge is going through a conductor in a second. This means current is actual "stuff" unlike potential, or voltage, which is a push that makes the "stuff" move.
AnswerThere is a misconception that 'potential' is the same as 'voltage'. This is incorrect. 'Voltage' is another name for 'potential difference', not 'potential'.
As an analogy, you can compare 'potential' with 'height', in which case 'voltage' (or 'potential difference') is equivalent to 'difference in height'. In the same way that 'height' is relative (i.e. it depends on its datum point, e.g. sea level), 'difference in height' is absolute. In the same way, the potential of an object depends on from where it is being measured (e.g. earth, or some other point), whereas voltage is absolute. So, regardless of the point of reference for the potentials of points A and B, the voltage between them will ALWAYS be the same.
So it is the voltage (potential difference) between two points, rather than potential at a point that 'drives' current.
If you equate voltage to a difference in height or a difference in pressure (according to your analogy), then current is the resulting flow.
yes
current flows as a result of potential difference i.e. in a circuit if there is no voltage difference between two points, no current can flow between those two points. So voltage has to be produced first.
The difference between current transformer and potential transformer is that the secondary of a current transformer can not be open circuited while under service whereas that of the potential transformer an be open circuited without any damage to the transformer.
Current flows in a circuit when there is a difference in electronic potential between two points.
voltage: it is the potentail difference between two wires. or it is the amount of energy used to force the electrons.current: it is the flow of free electrons.by Balaji,NITCAnswerThere is no such expression as 'potential voltage'. 'Voltage' is simply another word for 'potential difference'.
it is
Charge is potential, current is flowing.
If the potential increase and resitance remain the same ,the current will encrease
current flows as a result of potential difference i.e. in a circuit if there is no voltage difference between two points, no current can flow between those two points. So voltage has to be produced first.
Current will flow if there is a difference of potential energy and a path between those points.
Yes. This is the build up of charge. The difference in charge, aka the potential difference, is the driving force that causes current to flow. The third law of thermodynamics is in action when the circuit is completed and the current flows between two point as a result of the potential difference between those two points. (p.s. I am an American girl)
current is produced when there exists a potential difference between two points and d electrons move between these points.
Potential meter is voltage control device and rheostate is current control device. it is a basic difference.
If the potential difference between the ends of any conductor is doubled, then the current through the conductor is also doubled.

voltage
Voltage is the potential difference between positive and negative. Example (river) the potential difference between the top(mountains) and bottom(ocean) allows for current to flow the same goes for electricity
