Working of a Capacitor
The capacitance of a capacitor is measured in units called Farads. A capacitor is said to have 1 Farad of capacitance when the capacitor can hold 1 amp-second of electrons at 1 volt at a rate of electron flow of 1 coulomb of electrons per second. As 1 Farad is a big value, the capacitors are usually denoted in micro farads. Basic Capacitor ...
Capacitor
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, [1] a term still encountered in a few compound names, such as the condenser microphone is a passive electronic component with two terminals.

Neopixel Led Ring Ornament : 21 Steps (with Pictures
We want to wire the rings so that data from one ring feeds into the next, starting with the outer ring and heading inward. In other words, we want to connect the DO pad of the outer ring to the DI pad of the next inner ring, moving inward one ring at a time. To do this, I soldered lengths of stranded 22Ga wire between the pads as pictured.

Figure 11.7 A negatively charged particle moves in the plane of the paper in a region where the magnetic field is perpendicular to the paper (represented by the small [latex]×[/latex] ''s—like the tails of arrows).The magnetic force is perpendicular to the velocity, so velocity changes in direction but not magnitude. The result is uniform circular motion.

Formatting Research Paper Headings and Subheadings
But also make sure that your headings are consistent in structure and content: Switching between short keyword headings (e.g., "Experiment 2") and summary headings (e.g., "Mice Do not Recognize People") is confusing and never a good idea. Ideally, subheadings within a section all have a similar structure.
