Your question should really be the other way around! Technically, the correct term is 'potential difference'. Since this is measured in volts, over time it has also become known as 'voltage'. A similar thing has happened, but to a lesser extent, with 'power' which, being measured in watts, is often referred to as 'wattage'.
So, 'voltage' is simply another word for 'potential difference'. Originally, it meant 'potential difference expressed in volts' but, these days, it applies to microvolts, millivolts, volts, kilovolts, or megavolts!
Take care, however, not to confuse 'voltage' and 'potential'. These are different, and voltage should never be used when you mean potential.

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 symbol is used to measure potential difference?
V which abbreviates the word volt, which is the unit of measure of the difference in electromotive force (EMF), (or electric potential) between two points of contact; the resulting voltage difference could be direct current (DC) or alternating current (AC) depending on the source of the voltage difference.
When the current traveling through a resistor is increased what happens to the voltage that travels through the same resistor?
Your question reveals fundamental misunderstandings about the nature of electricity.'Voltage' is simply another word for 'potential difference', and a potential difference appears across opposite ends of the resistor; it doesn't 'travel through' that resistor! Current, on the other hand, DOES 'travel through' the resistor and is caused by the potential difference across the resistor.Resistance is the ratio of potential difference to current. So if the resistance remians unchanged when the current through it doubles, then it has happened because the potential difference has doubled.
What are potential transformer?
potential transformer is that which transforms one range of voltage (potential difference ) to another range without changing frequency.AnswerA 'potential transformer' is the North American term for what, elsewhere, is called a 'voltage transformer'. It, together with a current transformer, belongs to a class of transformers known as 'instrument transformers'.Potential transformers are used to (1) reduce the value of a high-voltage supply to a lower value (often 120 V) so that it may be read by ordinary voltmeters, and (2) to electrically-isolate the voltmeter from the high-voltage source for the purpose of safety.In electricity substations, potential transformers are also used to provide an input to certain types of protective relay.
What does a voltmeter actually measure in a circuit?
A voltmeter measures the electrical potential difference (voltage) between two points in a circuit. Here’s a closer look at what that means: Voltage Measurement Potential Difference: Voltage, or electrical potential difference, represents the work needed to move a unit charge between two points in a circuit. Essentially, it measures how much energy is available to push charges through the circuit. Units: Voltage is measured in volts (V). How It Measures Parallel Connection: A voltmeter is connected in parallel with the component or section of the circuit where you want to measure the voltage. This is crucial because the voltmeter must measure the potential difference across the component, not just the current passing through it. High Resistance: To avoid affecting the circuit, a voltmeter has a very high internal resistance. This high resistance ensures that minimal current flows through the voltmeter, so it doesn’t alter the circuit’s operation or the voltage being measured. Purpose in a Circuit Voltage Drop: It can measure the voltage drop across components like resistors, capacitors, and other elements in the circuit. This helps in understanding how the voltage is distributed throughout the circuit. Power Supply Voltage: It can also measure the voltage of power sources, such as batteries or power supplies, ensuring they are providing the correct voltage. Practical Use Troubleshooting: By measuring voltage at various points, you can troubleshoot electrical circuits, identify faulty components, and ensure proper circuit functionality. Design Verification: Engineers use voltmeters to verify that the voltage levels in a circuit match the design specifications.
What is another name for voltage?
Voltage can also be called "potential" and is measured across components or sections of a circuit.Answer'Voltage' is another word for 'potential difference', not'potential'!
What is potencial difference measured in?
The unit of measure is the Volt Potential difference is basically electrical "pressure" (an excess of electrons). Volt.....The unit of electric potential. Named after the Italian physicist Alessandro Volta (1745- 1827). The potential difference is the difference in charge at the poles of a current source The volt (symbol: V) is the SI derived unit of electromotive force, commonly called "voltage". It is also the unit for the related but slightly different quantity electric potential difference (also called "electrostatic potential difference"). ... en.wikipedia.org/wiki/Volt
What is a voltage of a battery?
It is the potential difference between the positive and negative terminals of the battery. The unit of electrical potential is the volt, so the difference in potential between two ponts is also a quantity with units of volts, colloquially called the 'voltage' between the points.
What is the relationship between voltage, potential difference, and electrical energy in a circuit?
Voltage, also known as potential difference, is the force that drives electrical current in a circuit. The higher the voltage, the greater the potential difference and the more electrical energy is transferred in the circuit.
How does a voltage divider work?
The essential circuit of a voltage divider, also called a potential divider, is:
What term describes potential difference?
Potential difference is also known as voltage, which is the force that drives electrical current through a circuit. It is measured in volts (V).
What is voltage also known as?
The term, 'voltage', is synonymous with 'potential difference'.Originally, the term 'voltage' was used to describe potential difference when specifcally expressed in volts. These days, however, we use the term whatever multiples or submultiples of volts are used -so it applies to potential difference whether expressed in microvolts, millivolts, volts, kilovolts, megavolts, etc.It's very important to understand that voltage is synonymous with 'potential difference', and not'potential'. So it would be quite incorrect to describe, say, the 'voltage at a point' in a circuit (e.g. "...the voltage at point A in a circuit is +12 V").
Is voltage the same as potential?
volt drop and potential difference are effectively the same thing, although the term volt drop is usually used in reference of what voltage has to occur for a diode to conduct, or what volt drop is expected across a long wire etc, potential difference is used to refer to the difference in voltage over a potential divider.
Is voltage the force that causes motion?
Voltage is the measure of the electric potential difference between two points in a circuit. It is not the force that causes motion directly, but it provides the potential energy needed to move electric charges through a circuit. The motion of electric charges in a circuit is driven by this potential difference, or voltage.
How is a voltmeter connected in a circuit to measure electrical potential difference?
A voltmeter is connected in parallel to the component or circuit being measured to measure the electrical potential difference, also known as voltage. This allows the voltmeter to read the voltage across the component or circuit accurately.
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 difference between EMF and terminal PD?

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.
