Where EMF is electromotive force, measured in the unit called a Volt, and where 'I' is the electrical current running on a circuit that points A and B are positioned in, and where R is the resistance of that circuit between points A and B, then
EMF=I x R, or "Volts" = "Amperes" times "Ohms".

What is the definition of betweenness of points?
The point B lies between points A and C is the distances AB, BC and AC are related by:AB + BC = AC.
If j and k are intersecting lines A and B are points on j and C and D are points on k how many planes contain points A B C and D?
exactly one
If AB equals 0 what is the angle between a and b?
Zero.For instance, given a right triangle with points ABC. where AC is the hypotenuse, then to find the angle between AB, we take sin(AB/AC), where AB is the distance between points A and B, and AC is the distance between A and C. If we replace AB with 0, the equation would be sin(0/AC). Sine of zero is always zero.
What is a ruler postulate?
Ruler PostulateThe ruler postulate states that: Every point on a line can be paired with a real number.The number associated with a point A on the line is called the coordinate of A.Two arbitrary points can be paired with the numbers 0 and 1, defining the length of a unit.The distance between any two points A and B is designated AB.The distance between two points A and B can be found by taking the absolute value of the difference of their coordinates: AB = |A - B|. Note that this implies that a distance is always positive.
Plot and connect the points A(-1, -5), B(6, -5), C(6, 2), and D(-1, 2).What is the difference between the length of BC and the length of AB?
B.2 units
What is the voltage between points B and C?
.75 V
Why voltage is measured between 2 points?
because voltage is the 'electrical potential difference'. since a "difference" can only be evaluated between two points so is voltage :)
What is the importance of voltage?
importance of voltage is the potential difference between two points.
What is produced first current or voltage?
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.
What is an electrical path between two points?
the answer is voltage
How do you find the voltage in physics?
The electrical presure between two points its called voltage
What came first the voltage or the current?
For a current to flow between two points, those points must have a potential difference (voltage) across them.
What is open circuit and short circuit?
Consider two points (A and B) in an electric circuit. An open circuit between A and B means there is no electrical connection between A and B. A short circuit between A and B means there is an electrical connection between A and B.
How are current and resistance related in a circuit?
The current between any two points in the circuit is the voltage between those two points divided by the resistance between the same points.
Why it is incorrect to say the voltage at point x is 12volts?
Voltage is the electrical potential difference between two points.
The movement of electrons between two points is called voltage?
No. "Voltage" is the difference of electric potential between two points ... the 'pressure' that electrons would feel to move from one point to another if there's a conducting path. The actual flow of electrons between two points is electric "current".
The length of is the between points A and B?
distance
