In this clip, you will learn how to create a simple constant current source so that all of your appliances are always running on the same current. This clip will explain exactly what this means and why you need to use it as well as how to set it up. Using the LM317LZ 100ma adjustible voltage regulator and one resistor, you can make a constant current source. With the LM317 1.5 amp version, you can make one with higher currents.

Eddy Currents are little circles of electricity created when metals are moved by magnets or even when magnets are moved by metals. To understand this practically take a regular piece of cardboard and drop it in between a horse shoe magnet. It drops normally with out being effected by the magnet. This is because the cardboard does not conduct electricity. Therefore it does not cause any eddy currents. But instead if you use an aluminum piece in the same way, it falls very slowly, because alumi...

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 defines the relationship between these three very important electrical properties. The host of the video further explains what voltage, current, and resistance are and how they work in relation to an electrical current. Gi...

Apple makes it simple to share your location with your family and friends using tools built into the "info" page for each conversation thread in Messages. With those tools, you can send your current location or share trackable real-time coordinates. But iOS always has a few hidden tricks to make things easier than they seem, and that's precisely the case if all you need to do is share your current location.
In order to make your own Tinted Moisturizer, you will need the following: lotion and foundation. In advance, you will need to select an appropriate foundation and moisturizer. The foundation that you choose should be very close to your current complexion. Mixing it with lotions will dilute it a bit, but it will still need to be close to your current complexion to blend in well.
This video gives a clear view of how well one has to answer in an interview. This is a good answer given by a woman interviewing for an environmental scientist position.
