DC positive polarity allows for a high level of penetration into the steel, while DC negative polarity means less penetration but a higher deposition rate (used on thin sheet metal, for instance). What does DC positive mean? The direction of … Continue reading →

Network adapters allow computers and other devices to interface with a local area network (LAN) or another type of network in order to access the internet. They can work with wireless connections like Wi-Fi or wired ones like Ethernet. A … Continue reading →

How Many Watts Do You Need? Not all PCs are built alike, so the amount of power each one needs is different. A high-end gaming PC will need more watts to run than a simple home office PC. This is … Continue reading →

Both brushed and brushless DC motors can be operated as generators. However, there are some important points to consider when designing the drive. How much power can a DC motor generate? It depends on how much current coil of rotor … Continue reading →

The Electrical Code prohibits AC and DC in the same box. You’ll need two distribution boxes – one for AC and one for DC. Circuit breakers rated for AC won’t work for DC. Expect to pay more for DC breakers. … Continue reading →

The laptop does not recognize the battery. Reset the AC adapter by following these steps: Unplug the AC adapter from the wall outlet for 15 seconds. Unplug the AC adapter from the laptop. Plug the AC adapter into a known-good … Continue reading →

One common issue with electrical outlets is reverse polarity, also known as “hot-neutral reversed.” In this condition, the outlet has been wired incorrectly, altering the flow of electricity. While the outlet will still be able to provide power to your … Continue reading →

5V power supplies (or 5VDC power supplies) are one of the most common power supplies in use today. In general, a 5VDC output is obtained from a 50VAC or 240VAC input using a combination of transformers, diodes and transistors. What … Continue reading →

12-volt batteries are commonly used as car batteries. One of the most common uses of a 12 volt battery is for transportation applications, such as in cars and boats. In these cases, the battery may be able to be recharged … Continue reading →

Not really, no. This is due to how fast charging works. Fast charging batteries have two phases of charging. The first phase is where they take in as much power as possible. Is it safe to use 65W charger? It’s … Continue reading →

“Ultimately, it’s really the amperage that determines how fast a charger will supply power to your device. If you want quicker charging, look for a wall or car charger that delivers 2100 mA of current at 5 volts (or whatever … Continue reading →

Routers, TVs, computers, electric stoves, electric clothes dryers — all can be damaged by lightning. Can lightning break a WiFi router? The only real risk to your router during a thunderstorm is a nearby or direct lightning strike, and whether … Continue reading →
