Hi! I''m confused. In the "Review" its says "When a capacitor is faced with an increasing voltage, it acts as a load: drawing current as it absorbs energy (current going IN THE NEGATIVE side and OUT THE POSITIVE side, like a resistor)", but the 4th picture shows
Capacitors Explained
If V = 1 Volt than C = Q, thus capacitance is defined as the amount of electric charge in coulomb required to raise its potential by one volt.If V = 1 Volt than C = Q, and Q = 1 Coulomb than C = 1 Farad thus one Farad is capacitance of a capacitor which stores a charge of one coulomb when a voltage of one volt is applied across its terminal.
In addition to the other answer: A larger capacitor on the output doesn''t decrease the average output voltage if the feedback loop is working properly. It does decrease the ripple on the output voltage (the ESR of the capacitor used also has an influence, and so do the switching frequency and the load). ...
What are capacitors? In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric. …

Introduction to Capacitors, Capacitance and Charge
What role does the inductor and output capacitor play in a ...
Supercapacitors, with their larger capacitance compared to traditional capacitors, are capable of rapid charge and discharge, allowing for the quick delivery of high currents when needed. The maximum voltage of some supercapacitors is typically …
As charge increases on the capacitor plates, there is increasing opposition to the flow of charge by the repulsion of like charges on each plate. In terms of voltage, this is because voltage across the capacitor is given by (V_c = Q/C), where (Q) is the amount of charge stored on each plate and (C) is the capacitance .
