What this chapter is about
In the previous chapter, we explored electric fields and forces between charges. While understanding forces is important, practical applications often focus on energy and voltage rather than forces. Batteries don't work by exerting forces on electrons; they work by creating potential differences that drive charges. Capacitors don't store charge; they store energy in electric fields. Understanding electrostatic potential and capacitance is essential for comprehending how electrical energy is stored, transferred, and utilized in every electrical device.
