Electric Potential Difference: Electric potential difference is the difference in electric potential between two points in an electric field. It represents how much work needs to be done to move a unit positive charge from one point to another.
Potential Differences: Potential differences are variations in electric potential within an electric field. They can occur due to different charges or distances between charges.
Electric Field: An electric field is a region around charged particles where other charged particles experience forces. It determines how charges interact with each other and affects their motion.
