Power Resistor Basics The power dissipated by a resistor can be found using Joule’s first law (Power = Voltage x Current). The dissipated power is converted to heat and increases the temperature of the resistor. The temperature of a resistor keeps climbing until it reaches a point where the heat dissipated through the air, circuit board, and the surrounding environment balances the heat generated. Depending on the required wattage, a device may need a high-power resistor to prevent overheating....

Benefits of Renting Mobile Broadband While Traveling Having high-speed internet access directly from your laptop is very convenient – it gives business travelers critical “anywhere, anytime” Internet access. It’s also, however, much more expensive than going to a Wi-Fi hotspot, signing up for global Wi-Fi service, or renting a workstation at an internet cafe. International Mobile Broadband Providers Below are a few companies from whom you can rent Internet access internationally....

Dedicated camera hardware still gets way better results than your iPhone or Pixel camera, but sometimes that doesn’t matter.

Smartphones already use more battery when using the internet than when not, but a hotspot demands much more than the phone’s standard internet use. The phone is not only relaying data from in and out of its hotspot network but also sending information to the connected devices. If you make heavy use of the hotspot feature of your phone and battery life is an ongoing issue, it might just make sense to get a separate mobile hotspot device or a travel wireless router....

What Is a Dash Cam? A dash cam is a camera mounted to your car’s dashboard that continuously records the events happening outside your windshield. They use your vehicle as a power source to record everything in their field of view. Dash cam videos are generally high quality, providing clear evidence in the case of theft, vandalism, and unexpected incidents. They’re also helpful for recording pleasant, scenic journeys. In many cases, dash cam video can be uploaded to the cloud and shared with insurance companies or the police as evidence after an incident....

Sony did focus on racially diverse characters and female protagonists this time around, though, and while the effort may not drive blockbuster sales in the current economy, it’s necessary for a more inclusive gaming community.

Chipmaker Qualcomm recently unveiled its latest Snapdragon processor, which has a feature that could keep front-facing cameras on all the time. The company says the camera offers convenience.

At a remarkable 49", the CHG90 display is large enough to easily fit three apps side by side or to fill your peripheral vision for a truly immersive gaming experience. Samsung promotes the monitor mainly for entertainment, with a speedy 1ms response time, FreeSync 2 technology, High Dynamic Range (HDR) support, and other gaming-specific features. It’s not quite as impressive when displaying text, however — on a screen this size, even the 3840 x 1080 resolution isn’t quite enough for pin-sharp fonts....
