In this video, we learn how to use high voltages using the Wimhurst machine. First, you must have a spinning wheel, double ended brushes, collecting combs, leyden jars, adjustable electrodes, and small metal plates. Once you connect all these together, you will notice the brushes on either side are perpendicular to each other and the wheel spin in opposite directions. Spin the wheel and then listen to the sound it makes. The plate will then charge with different electrons and create positive ...
This video shows how easy it is to jump start a car properly. Locating the car manual is the first thing to do. It will help for that particular car. Inspect the dead battery. If the battery is cracked or if the liquid inside of it is frozen, don't jump the cars. The battery could explode. Position the cars so that the batteries are as close as possible. Connect the positive cable (red) to the positive terminal (+) of the dead battery. Connect the other positive cable to the positive terminal...

After learning that you'll need to spend at least $74 on a special charger and a USB Type-C Lightning cable to enable fast charging on the new iPhone X and iPhone 8 models, you may be wondering why you can't just use the standard Lightning cable. While we can't answer why Apple didn't include the USB-C cable in the box with their new phones, we can explain why you need USB-C to enable fast charging.
When Apple announced the iPhone X, 8, and 8 Plus, they had a laundry list of new features to talk about. They discussed the improved camera, the new screen, wireless charging, and many other things, but they curiously failed to mention that they just matched one of biggest features Android has touted over Apple for years — fast charging.
Before the iPhone 7 models were released, there were many rumors pointing to the inclusion of wireless charging, which obviously didn't happen. Now the rumor mill is back at it again for Apple's next smartphone, most likely being called the iPhone 8, and the possibility of wireless charging is more certain this time.
My OnePlus One easily gets over a day of battery life without a problem, but when I try to charge it, it seems to take just as long. For some reason, no matter what charger you plug your OPO into, it never gets more than USB-level power, meaning that charging times are more than double when compared to traditional AC-charging.
In this rapid fire video, Mr. G introduces us to the idea of atoms, static electricity, and opposing charges.

Despite their awkward appearance, Apple's AirPods have become the earbuds of choice for working out, largely thanks to quality audio without any wires to tangle. However, at $159 to start, they aren't exactly for everyone.
Before the iPhone 7 was launched and all the unrealized reports about the phone's features were tucked back into their annual rumor mill, there was some speculation about wireless charging. Specifically, whether or not the iPhone 7 and 7 Plus would support it. We now know they don't, and here's why.
If you've ever had issues charging your iPad, iPhone, or iPod touch, like most other Apple products, the culprit to blame is usually a frayed or damaged cable. It's a common design flaw due to the thinness of the cords and the weak sheath surrounding them — but that's not always the problem.
In the first video, you'll see how contact between different materials can result in attraction or repulsion. Experimental results are discussed that led to Ben Franklin's one fluid theory of electricity. It explains how clues were found from rubbing different materials together.
After many years of rumors, the second-generation iPhone SE is here. At $399, it is the most inexpensive iPhone Apple has sold since the original iPhone SE came out. And while the new SE comes with Apple's typical five-watt power adapter, the smartphone supports fast charging — you just need to get a fast charger separately.
Compared to the original AirPods, Apple's second-generation AirPods have better battery life, Hey Siri support, a more stable connection, faster switching between devices and call connections, less latency for gaming, and an optional Wireless Charging Case. If you plan on preordering the new model, you might want to skip the Apple Store and opt for Amazon instead to get it at your door quicker.
Will smartphone batteries ever last as long as we need them to? Perhaps not. That's why we rely on external batteries to help us stay connected for hours, even days, longer than usual. But in 2018, you don't want to use just any external battery. Modern Android phones have fast charging — so should your portable charger.
The fact that this guide even exists is a downright shame, but that's neither here nor there. The truth of the matter is the iPhone 7 and 7 Plus don't have 3.5 mm headphone jacks, and since they use the Lightning connector to output audio, it's hard to charge your phone while your headphones are plugged in.
When the power goes out, having the ability to contact others becomes extremely important, and your cell phone can be one of the most important tools to have. But if the power is out for an extended period of time, battery life becomes a constant problem.

The Galaxy S20's Wireless PowerShare is a must-use feature. With even the base model packing a 4,000 mAh battery, you have more than enough juice for all your Qi-enabled devices. The default settings make it so that in certain situations, you may have to choose between your phone or wireless earbuds, but you can change that.
If you just got a new iPhone, chances are you picked up the iPhone 11, successor to the iPhone XR, the most popular device in Apple's 2018 series.

Simple yet effective, capacitors come in a dizzying array of forms and materials, vital to so many circuits for storage, timing, and filtration - the mighty capacitor!
Nicad batteries often die in such a way that they won't take a charge and have zero voltage. This usually means they're shorted out by crystal dendrite growth. Here's a method of bringing them back to life by zapping those shorted crystal dendrites away with too much current and/or voltage. We'll use a welder as a power source. You could also use a car battery, a DC powersupply, or almost anything with some voltage. Charged-up capacitors are popular for this because you can get a very fast pu...
