electric potential is potential difference between two points in closed circuit.
but electromotive force is potential difference in any open circuit.

Electrical potential refers to the electric potential energy per unit charge at a point in an electric field, measured in volts. Electromotive force (emf) is the energy per unit charge supplied by a source of electrical energy, such as a battery, to drive current through a circuit, also measured in volts. Essentially, electrical potential is a property of a point in the field, while emf is the force that drives the flow of charge.

What is a measure of electromotive force called?
A measure of electromotive force is called voltage. It represents the potential difference between two points in an electrical circuit and is typically measured in volts (V).
What does voltage mean in science?
In science, voltage is a measure of the electric potential difference between two points in a circuit. It represents the force that drives an electric current to flow from one point to another. Voltage is measured in volts (V).
What does volt measure?
Volts measure the difference in electric potential between two points in a circuit. It represents the force that drives electric current through a circuit.
What instrument do you use to measure electrical force?
A voltmeter is typically used to measure electrical force, which is also known as voltage or electromotive force. It provides a numerical value indicating how much force is being exerted in an electrical circuit.
Will there be a current between the two points if the electrical potential energy at one point in a circuit is greater than the electrical potential energy at another point?
Yes, there will be a current flowing between the two points if there is a difference in electrical potential energy. This potential difference causes charges to move and create an electric current to balance out the potential energy.
What is a measure of electromotive force called?
A measure of electromotive force is called voltage. It represents the potential difference between two points in an electrical circuit and is typically measured in volts (V).
Which is more common in practical cases electric potential or potential difference?
EMF (electromotive force) is more useful, in fact vital, for any electrical or electronic circuit. At school level your teacher would not make a distinction (and probably doesn't know the difference, or even realise there is one) between electromotive force and potential difference. In answer to a school question, it's potential difference.
Difference between voltage and emf?
'Voltage' is simply another term for 'potential difference', and an electromotive force is the open-circuit, or no-load, potential difference of a source such as a battery or generator.
What cause an electric current to move through a wire?
An electromotive force or potential difference between its ends.
What causes the flow of electric current?
Electromotive force (potential difference, voltage) between two points of a conductor.
What does voltage mean in science?
In science, voltage is a measure of the electric potential difference between two points in a circuit. It represents the force that drives an electric current to flow from one point to another. Voltage is measured in volts (V).
What does volt measure?
Volts measure the difference in electric potential between two points in a circuit. It represents the force that drives electric current through a circuit.
Define voltage in electrical?
Voltage (of a circuit) as defined in the NEC: n. The greatest root-mean-square(rms) (effective) difference of potential between any two conductors of the circuit concerned. Voltage as defined by Webster's: n. Electromotive force or potential difference, usually expressed in volts.
What is the difference in electrical potential energy between two places in an electrical field?
voltage
What is the difference between EMF and terminal PD?
An electromotive force is the potential differenceappearing across the terminals of a battery, generator, etc., when that device is not supplying any load. When the device is supplying a load current, the electromotive force is equal to the sum of the voltage drops around the complete circuit, including any internal voltage drop.A potential difference (also known as a 'voltage'), as the name implies, is the difference in potential between two points.
What instrument do you use to measure electrical force?
A voltmeter is typically used to measure electrical force, which is also known as voltage or electromotive force. It provides a numerical value indicating how much force is being exerted in an electrical circuit.
Will there be a current between the two points if the electrical potential energy at one point in a circuit is greater than the electrical potential energy at another point?
Yes, there will be a current flowing between the two points if there is a difference in electrical potential energy. This potential difference causes charges to move and create an electric current to balance out the potential energy.
