What is an electric potential difference?
1 Answer
Electric potential difference, often referred to as voltage, is a fundamental concept in the field of electricity and magnetism. It represents the difference in electric potential energy per unit charge between two points in an electric field. In simpler terms, it's the amount of work done to move a unit positive charge from one point to another against the electric field.
Mathematically, electric potential difference (ΔV) is defined as:
ΔV = V₂ - V₁
Where:
ΔV is the electric potential difference between two points.
V₂ is the electric potential (voltage) at the second point.
V₁ is the electric potential (voltage) at the first point.
The unit of electric potential difference is the volt (V), which is equivalent to one joule of energy per coulomb of charge. In essence, the electric potential difference tells you how much energy is required to move a charge between two points in an electric field. If the potential difference between two points is 1 volt, it means that 1 joule of energy is required to move 1 coulomb of charge from one point to the other.
Electric potential difference plays a crucial role in understanding and analyzing various electrical circuits, devices, and systems, as it determines the flow of electric current and the distribution of charges within a circuit.
