Another simple review of the vector dot product, for those of you that have forgotten. The operation that involves multiplying two vectors together can be done in a few ways. The first operation is called either the scalar product or the dot product. One of the well known definitions looks like this: RULE 1: This [...]
This is a very simple post and a very simple subject, but every once in a while even the experts need to be reminded how to do simple addition and subtraction with vectors. Let’s go ahead and specify a couple vectors that we can work with. Vector In MATLAB: >>A = [1 2 4]; Vector [...]
Capacitance is an ability of an electronic component to store energy in the form of an electrostatic charge (electric field). It is often described as a characteristic of a component that opposes any change in voltage. Capacitor stores energy in an electric field between two parallel metal plates which are separated by an insulator (dielectric) [...]
Inductance is the ability of a component with a changing current to induce a voltage across itself or a nearby circuit by means of a changing magnetic field. Inductance (measured in Henries) is an effect which results from the magnetic field that forms around a current-carrying conductor. It also can be thought of as the [...]
Much of what you will work with in electronics requires alternating current, meaning you will encounter sine waves, square waves, and triangle waves. It might have been a few years since trigonometry, but you will quickly realize that mastering the basics of trigonometry is essential for your success in electrical engineering. Sine functions are one [...]
