What is electric potential difference?

The electric potential difference, also known as voltage, is the measure of the electric potential energy per unit of charge that is available to move electric charge between two points in an electric field. It is typically measured in volts (V).

Electric potential difference is the driving force that causes electric charge to flow through a conductor, such as a wire. It is the difference in electric potential energy between two points in an electric field. When there is a potential difference between two points, an electric current will flow from the point of higher potential energy to the point of lower potential energy, as the charges seek to lower their potential energy.

Electric potential difference can be created in a number of ways, such as by separating electric charge (as in a battery), by applying mechanical work (as in a generator), or by exploiting the thermoelectric effect (as in a thermocouple).

The electric potential difference between two points is also known as the electric potential difference, the voltage difference, or the voltage drop. It is the difference in electric potential energy per unit of charge between two points.

The electric potential difference between two points is directly proportional to the amount of electric charge that flows between the points. The greater the electric potential difference, the greater the electric current that will flow.

Electric potential difference is an important concept in electricity and electronics, as it is the driving force that causes electric charge to flow through a conductor.

The electric potential difference across a conductor is determined by the resistance of the conductor and the amount of electric current flowing through it, according to Ohm's Law.

Electric potential difference can be measured using a device called a voltmeter. A voltmeter is connected in parallel with the circuit element being measured, and it measures the electric potential difference across the element.
