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...
In an old video posted on YouTube, about how to make a speaker in a tissue box, they got a Kleenex box, foil, motor, and battery. Of course the motor ran off the battery and it made a sound, but there's no way to just plug in the audio jack from your Apple iPhone into the Kleenex box where it's contacts obviously aren't going to touch any electrical contacts and have it work. It's not possible.
This year, there's no need to waste time and energy stringing colorful Christmas lights all over your home and yard. All you need is the Circuit Marker from AgIC, a Japanese technology company, and you're ready to deck the halls.
In this video, we learn how to properly balance chemical equations. You will see what substances are in each side of the equation. You will then need to count the atoms that are on each side of the chemical equation. Once you write down the number of atoms on each side, you will need to even them out. To do this, you need to change the coefficients within the equation. These change the total number of atoms inside of a chemical. Once you do this, you will add more to each atom present and the...
Watch this science video tutorial from Nurd Rage on how to make copper sulfate from copper and sulfuric acid in three ways. They show you how to make copper sulfate from copper and sulfuric acid using two chemical methods and one electrochemical method.
In this video, we learn how to balance chemical equations using a simple method. Start out by writing your two chemicals next to each other. After this, you will need to write out how much of each atom each of the chemicals has. Now you will have a better idea of how you need to balance out each of the different equations. Make a chart of all the elements that are involved, then you can solve it. Use simple addition to add together the atoms of each and then write out the correct answer in th...
In this video we learn how to balance chemical equations the fun way. First, remember that matter cannot be created or destroyed. Take two different types of chemicals and put them on opposite sides of the equation. If you have more mass on one side than the other, these will not balance out. Once you have equal amounts of mass on both of the sides, you will be able to balance the chemical equation. Remember this rule whenever you are balancing out chemical equations. Use visual markers to he...

This video will benefit those viewers who want to lea...
Gary Bunzer the RV Doctor shows how to avoid potential RV problems by cleaning your electrical hookup cord. Before you connect your RV to an electricity supply, make sure to clean and brighten the metal contacts on your shoreline cord. Use fine-grade steel wool to clean all surface corrosion off your cord's prongs. You can also use sandpaper, emery cloth or any other gentle abrasive. After you get the metal prongs clean and shiny, use a dauber or brush to coat the surface of the prongs with a...
There's more than one way to test a fuse, and it doesn't have to be expensive. In this video tutorial, see how to test an electrical fuse with a screwdriver tester or multi-meter. A test screwdriver is relatively cheap and simple to use. A multimeter is a little more expensive and a little more complicated, but once you get used to it, fairly simple.
The Type G plug is the standard plug in the United Kingdom, usually 230V and 50Hz, and is referred to as the BS1363 (British Standards 1363). It's most commonly referred to as the "13-amp plug" because it has a 13-amp fuse inside. The wires consist of a hot (or live) wire, neutral wire, and an earth (or ground) wire.

Build a faraday motor with tips from this how-to video. In the early 1800s, physicist Michael Faraday invented the first device to convert electrical energy into mechanical motion. This is an easily built version of his motor. The magnet sets up a magnetic field, and the electrical current through the screw sets up a separate electromagnetic field around the screw. The two fields react and the result is rotation.

Samsung's not one to make drastic changes to what already works. They've continued on with the IP68 rating under IEC 60529 first given to the Galaxy S8 all the way to the the Galaxy Note 10. If you're a little confused as to what this rating means, don't worry, it's actually pretty simple once you get to the meat and bones of it.
When it comes to resistance to the elements, Samsung seems to believe in the old saying "if it ain't broke, don't fix it." They've carried over the IP68 rating under IEC 60529 that was first found on the S8 all the way to their tenth-anniversary flagship, the Galaxy S10. While this certainly sounds great on paper, it's natural to want to dig a little deeper and find out what the rating means.
Plants all around us capture sunlight every day and convert it to energy, making them a model of solar energy production. And while the energy they make may serve the needs of a plant, the process isn't efficient enough to generate power on a larger scale. So, scientists from the University of California found a way to treat bacteria with chemicals that turned them into photosynthesis machines, capable of generating products we can convert into food, fuels, and plastics.
In this tutorial, we learn how to balance chemical equations. The first thing you want to do is to draw a graph and label one side reactants and the other side products. Go through each of the atoms that are in your equation on both sides. Write out how many atoms are in each chemical. Then, find a common multiple that will give you and equal amount on each side of the equation. Continue to do this same for all the chemicals in your equation, then when you are finished write it out. Now you w...
