How to Find Capacitance

The capacitance of an object is the ability for it to hold electric charge. Capacitance is related to charge and electric potential by the relation C=QV.{\displaystyle C={\frac {Q}{V}}.} Assuming the existence of an electric charge Q,{\displaystyle Q,} finding the capacitance of an object will therefore require the calculation of the electric field and its associated potential before evaluating. The capacitors in this article all exhibit some form of symmetry, which allows for the electric field to easily be evaluated. (Almost all problems using Gauss's law require some form of symmetry for the integrals to be evaluated analytically.)

How to Calculate Series and Parallel Resistance

Need to know how to calculate series resistance, parallel resistance, and a combined series and parallel network? If you don't want to fry your circuit board, you do! This article will show you how in just a few easy steps. Before reading this, please understand that resistors do not actually have an "inside" and an "outside" to them. The use of "in" and "out" is merely a figure of speech to help novices understand the wiring concepts.

How to Solve Parallel Circuits

Solving parallel circuits is an easy process once you know the basic formulas and principles. When two or more resistors are connected side by side the current can "choose" it's path (in much the same way as cars tend to change lanes and drive alongside one another when a one-lane road splits into two parallel lanes). After reading these steps you should be able to find the voltage, current and resistance between two or more resistors in parallel.
