Circuit analysis, or solving a circuit, means figuring out voltages and currents in each element. Here's an overview of circuit analysis, with some context for the various tools and methods we …

Circuit analysis is the process of finding all the currents and voltages in a network of connected components. We look at the basic elements used to build circuits, and find out what happens …

We are developing methods for analyzing a circuit. So far we've defined the most common components (resistor, capacitor, and inductor) and sources (voltage and current). Now we …

Learn about electricity, circuit theory, and introductory electronics. We also have sections that let you get down and dirty with household items, from building your own robot to videos where we …

With the principle of superposition you can simplify the analysis of circuits with multiple inputs. Written by Willy McAllister.

Introduction Linearity is a mathematical concept that has a profound impact on electronic design. The idea itself is quite simple, but the implications have great meaning for our field. First we …

One place gigantic currents pop up is when you simulate a circuit. The computer doesn't mind a current of a zillion amperes, but it's probably not what you intended.

A summary of the math and science preparation that will help you have the best experience with electrical engineering taught on Khan Academy. Become familiar with engineering numbers …

That's the rhythm of how we're going to use this equation to help us solve circuits. One small point I want to share, notice that in both these equations the sine comes first?

A voltage divider is a simple series resistor circuit. It's output voltage is a fixed fraction of its input voltage. The divide-down ratio is determined by two resistors. Written by Willy McAllister.
