Grow Silver Metal Crystals by Electrochemistry

Greetings fellow nerds. In this video, we’re going to grow tiny crystals of silver metal under the microscope. We’re going to grow the crystals by electrochemistry. The setup is actually very simple. I’ve tapped down an aluminum wire cathode and a silver wire anode to this plastic tray. It’s connected to these batteries through a […]

EQUIVALENT RESISTANCE 3 | VERTICAL SYMMETRY | Hindi | English Subtitles [CC]

Now let’s talk about vertical symmetry Now you can see that vertically this figure is symmetrical If we draw a line like this both halves will be symmetrical vertical symmetry is present when a mirror divides the circuit in such a way to produce mirror images and “a” & “b” lies on the opposite sides […]

Electric Circuits – Water Analogy | Hindi

Today we’re going to discuss series and parallel circuits. And to do so, we’re using a water analogy. We use this analogy because we can see water, and it’s very hard to see electrons and how electrons flow through a circuit. Now let’s go in the lab and explore how we made this analogy come […]

Army discovery may offer new energy source

Army scientists and engineers recently made a discovery. An aluminum nano material of their design produces high amounts of energy when it comes in contact with water or any liquid containing water. During routine materials experimentation at the U.S. Army Research Laboratory at Aberdeen Proving Ground, Maryland, a team of researchers observed a bubbling reaction […]
