Each learning path is one chapter: a guided route through a topic, one small course at a time. Pick a class to see its chapters in order.
A camera flash stores energy in a capacitor and releases it in a blink. Behind it are potential, the energy a charge has in a field, and capacitance, how much charge a pair of conductors can hold. In this chapter you learn potential and equipotentials, what conductors and dielectrics do in a field, and how capacitors store, share and lose energy. Python finds the potential of many charges and charges a capacitor step by step.
