It is a line segment.
The length of a straight line between those two points.
The current between any two points in the circuit is the voltage between those two points divided by the resistance between the same points.
Current will flow if there is a difference of potential energy and a path between those points.
Those would be the "equinoxes".
Voltage is always measured between two points because it represents the difference in electric potential between those two points. This difference in potential is what drives the flow of electric current in a circuit.
Voltages are always measured between two points because voltage is a measure of the difference in electric potential between those two points. This difference in potential is what drives the flow of electric current in a circuit.
For a current to flow between two points, those points must have a potential difference (voltage) across them.
-- the voltage between the two ends of the circuit -- the resistance between those points
You would need to know the distance travelled between two fixed points and the time taken to travel between those two points.
To determine the potential difference between two points in a circuit, you can use a voltmeter. Connect the voltmeter across the two points you want to measure and the reading displayed on the voltmeter will indicate the potential difference between those two points.
