There are 7 basic logic gates : AND, OR, XOR, NOT, NAND, NOR and XNOR. But there are only two universal gates ( you can get any boolean expression ( true or false , 0 or 1) from these gates ) which …

Between the 18th and early 19th century, before scientists could observe electrons, they believed that electrical charge flowed from positive to negative. They then learned, sometime in the 1850s or …

Here is a summary of the math and science preparation that will help you have the best experience learning the electrical engineering topics taught on Khan Academy.

Let's explore the mysteries of light and electricity. From how light reflects, to correcting defects in our eyes. From understanding charges to lighting up cities. From Newton's prism to Faraday's generator, …

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 when …
