Since Potential Difference is measured in Volt(V),Work Done in Joule (J) and Charge in coulomb(C). We can say 1 Volt = 1 Joule/1 Coulomb 1 V = 1 J /1 C Hence, 1 Volt is amount of potential difference produced when 1 Joule of Work is done to move 1 Coulomb of Charge from One point to another, in an electric circuit.
An electron accelerated through a potential difference of 1 V is given an energy of 1 eV. It follows that an electron accelerated through 50 V is given 50 eV. A potential difference of 100,000 V (100 kV) will give an electron an energy of 100,000 eV (100 keV), and so on.
A cell makes one end of the circuit positive and the other negative. This sets up a potential difference (p.d.) across the circuit. The potential difference across a component in a circuit is defined as: The energy transferred per unit charge flowing from one point to another. Potential difference (sometimes called voltage) is measured in volts ...
Potential difference (or voltage) is a measure of energy, per unit of charge, transferred between two points in a circuit. A potential difference of 1 volt means that 1 joule of work is done per ...
Example 2: Potential Difference in a Circuit. Consider a circuit with an electric field strength of 8000 volts per meter and a distance of 0.1 meters between the two points.

The potential difference formula, V=W/Q, is pivotal in both everyday life and industrial settings. Here are some key applications: Designing electrical circuits. Engineers use the formula to determine the necessary voltage for achieving desired current flows through various components. This ensures that circuits function correctly and efficiently.
Potential Difference formula:** V = I x R** The potential difference (which is the same as voltage) is equal to the amount of current multiplied by the resistance. A potential difference of one Volt is equal to one Joule of energy being used by one Coulomb of charge when it flows between two points in a circuit.
The unit of electric potential difference is the joule per coulomb (J/C), which is also termed as volt (V). Analogy / Example.

Potential difference is a scalar quantity. The other unit of potential difference is volt. 1 volt = 1 joule / coulomb. That is, If 1 joule / coulomb of work has to be done in taking a test charge from one point to another in an electric field, then the potential difference between those points will be 1 volt. If B is also at infinity then,
