The potential difference between points A and B, \(V_{B}-V_{A}\), is thus defined to be the change in potential energy of a charge \(q\) moved from A to B, divided by the charge. Units of potential difference are joules per coulomb, given the name volt (V) after Alessandro Volta.
Learn what potential difference is, how to measure it, and how to calculate it using the formula V = I x R. Potential difference is the same as voltage and is measured in volts (V).
What is Voltage? Voltage (also known as electric potential difference, electromotive force emf, electric pressure, or electric tension) is defined as the electric potential difference per unit charge between two points in an electric field.Voltage is expressed mathematically (i.e. in formulas) using the symbol “V” or “E”.

Basic Formula. The potential difference (V) between two points in an electrical circuit can be calculated using the formula: V = W/Q. Where: – V is the potential difference (voltage) measured in volts (V), – W is the work done (or energy transferred) measured in joules (J), – Q is the charge measured in coulombs (C). Ohm’s Law

The formula for calculating potential difference is V = I x R. Derivation of Potential Difference Formula – Assume there are two entities, A and B. A has +C, which is the positive unit charge that travels to body B. Some work is done while the charge moves from A to B. The POTENTIAL DIFFERENCE is the effort done while replacing +C from A to B.

Calculate the potential difference using the formula above and the work and charge from steps 1 and 2. FAQ. What is a potential difference? A potential difference is also often referred to as the electric potential. It’s a measure of the electric potential energy contained within a closed circuit or system.
Another way to find electric potential difference formula is to find the electric potential at points A and B, then subtract accordingly. Electric potential difference is an algebraic value and is ...
Voltage is not the same as energy. Voltage is the energy per unit charge. Thus, a motorcycle battery and a car battery can both have the same voltage (more precisely, the same potential difference between battery terminals), yet one stores much more energy than the other because [latex]\text{Δ}U=q\text{Δ}V.[/latex] The car battery can move more charge than the motorcycle battery, although ...
Dimensional Formula of Potential Difference. From the definition discussed above, the potential difference can be written as : ΔV= Δ W/Q. Q = electric charge. W = work done. So, dimension of potential difference= dimension of work done / dimension of electric charge. W= F.S. So, dimension of W = [MLT-2] x [L] = [ML 2 T-2]
