The first video introduces the basic electrical quantities of charge, current, voltage, and resistance. The concept of quantities and units is explained. The units of Coulombs, Volts, Amperes, and Ohms are described. The three basic formulas of Ohm's Law (E=IR, I=E/R and R=E/I ...more
Math scares a lot of would-be electronics lovers away from the field, and if you really hate math this is probably the video in this series where you stop. It will teach you how to use Ohm's Law to calculate resistance and how that applies to a basic circuit.
This video teaches the basics of Ohm's law, which is an important equation in electrical engineering. The three variables which are used in this equation are V, which stands for voltage, I for current, and R for resistance. The equation for the law itself is I=V/R. This law de ...more
Watch this educational how to video to review Ohm's Law. This math and physics concept is derived from electric motive forces, intensity of current flow and resistance values of conductor. Watch and learn more about Ohm's Law.
Calculating resistance and power isn't hard... and, as David explains, knowing Ohm's Law and the Power Triangle can be darn useful when you're designing a project, sorting out power supply issues, or want to keep from burning your car down.
This video introduces the formulae for watts in an electric circuit, P=IxE, P=I^R, and P=E^/R. It also explains how P=I^R and P=E^/R are algebraically derived from P=IxE and Ohm's Law.
If you're an electrical engineer, you needn't worry about this educational video, but if you aren't... Watch this tutorial to see how to use an oscilloscope and function generator. Learn all about how to use one of these oscilloscopes with this brief introduction to its work ...more
Got a knack for speeding? Like running red lights? Believe or not, the police have better things to be doing than pulling you over, like catching real criminals. That's why more and more cameras are popping up at known speeding zones and on street corners—so the cops can clean ...more
