Understanding the Basics of Electric Potential
Electric potential refers to the amount of electric potential energy that a charged object possesses per unit charge.
It is a fundamental concept in the study of electromagnetism and plays a crucial role in understanding the behavior of electric fields and circuits.
The electric potential at a point in space is determined by the electric field generated by nearby charges.
It is defined as the work done in moving a unit positive charge from infinity to that point in the electric field.
The SI unit for electric potential is the volt (V), named after the Italian physicist Alessandro Volta, and is defined as one joule per coulomb.
In scientific notation, electric potential is often denoted as V or φ.
This measurement allows scientists to quantify the relative difference in electric potential between two points in a circuit or an electric field.
