In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone. It is a passive electronic component with two terminals.

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

8.2: Capacitance and Capacitors

The current through a capacitor is equal to the capacitance times the rate of change of the capacitor voltage with respect to time (i.e., its slope). That is, the value of the voltage is not important, but rather how quickly the …

Capacitors Basics

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. …

21.6: DC Circuits Containing Resistors and Capacitors

When there is no current, there is no (IR) drop, and so the voltage on the capacitor must then equal the emf of the voltage source. This can also be explained with Kirchhoff''s second rule (the loop rule), discussed in Kirchhoff''s Rules, which says that the algebraic sum of changes in potential around any closed loop must be zero.
