The simple answer: the potential at a point some distance, r from a monopole is

kQ / r,

where k is Coulumb's constant: 9.0E9

Q is the charge of the monopole

and r is the distance from the monopole. And how to get there: Since electric force is kq1q2/ r2, the electric field ( Force per charge) is kQ/r2. The voltage of a particle is defined to be the integral of the electric field with respects to r. Thus integrating you get the above equation.

What variable represents potential difference?

The variable that represents potential difference is V, which stands for voltage.


How can you get the largest voltage difference?

There is no such thing as a 'voltage difference'! 'Voltage' means 'potential difference', so what you appear to be asking is "How do you get the largest potential difference difference?'! Potential difference is caused by the separation of charges between two points. The greater the amount of charge separation, the greater the potential difference.

Potential difference.


What is the potential difference measured in volts?

'Force' isn't measured in volts. Potential and potential difference are measured in volts.


What is the abbreviation of potential difference?

The abbreviation of potential difference is V, which stands for voltage.


What can be converted to energy?

Anything with potential difference could create the flow of energy. A potential difference could be electropotential, chemical potential or potential difference between high and low ground like energy from water fall. A potential difference can exist in the form of motion difference between a stationary and a moving objects.


What is the unit of potential difference?

The unit for electric potential difference is the volt (V).


What is the potential voltage?

Unless you are using 'potential' in the general sense (i.e. "What is the possible voltage?"), there is no such engineering term as 'potential voltage'. Voltage is a synonym for 'potential difference', so your expression would then mean "What is the potential potential difference?"Do not mix up 'potential' with 'potential difference' (voltage); they are two different things.


What is used to measure potential difference?

A Volt meter is used to measure potential difference (a.k.a. voltage). Potential difference is measured in units called: Volts (V).


How does an electron accelerate when subjected to a potential difference?

When an electron is exposed to a potential difference, it experiences a force that causes it to accelerate in the direction of the potential difference. This acceleration is due to the electric field created by the potential difference, which exerts a force on the electron, causing it to move.


What are the differences between voltage and potential difference?

Voltage is the potential difference to the ground. By convention, ground potential is zero volt.The above answer is incorrect. 'Voltage', by definition, is potential difference. It has nothing to do with being measured with respect to ground -in fact potential difference (voltage) cannot be measured with respect to anything.


Are potential difference and voltage always the same?

Voltage is simply another word for potential difference.
