How does a switch mode power supply work? In switching power supply designs, the input voltage is no longer reduced; instead, it’s rectified and filtered at the input. Then the voltage goes through a chopper, which converts it into a … Continue reading →

If the GPU requires more than 150 watts, it will come with an 8-pin connector or two 6-pin connectors. As always, there are exceptions. The most power-hungry graphics cards will come with a 6-pin and an 8-pin connector. Do I … Continue reading →

If there is a commutator and brushes, it may be either a DC motor or an AC commutator motor (Universal motor). However, if the stator core is also laminated in the presence of commutator, then it is likely to be … Continue reading →

A simple model for a DC motor is V=R∗i+e, where V is the terminal voltage, R is the motor resistance, and e is the back-emf voltage. How do you find the voltage of a motor? It states that current through … Continue reading →

We also saw fairly similar noise levels across all 12 of the cooling pads, with noise levels ranging from 48 to 55 decibels. In our lab, which has an ambient noise level of 40 to 43 decibels, that was loud … Continue reading →

Yes, a cooling pad really works and it’s worth buying one for your MacBook because too much heat can damage it’s components and a cooling pad will keep it cool and safe. Are cooling pads really worth it? They can … Continue reading →

Disadvantages of Solar Energy Cost. The initial cost of purchasing a solar system is fairly high. Weather-Dependent. Although solar energy can still be collected during cloudy and rainy days, the efficiency of the solar system drops. Solar Energy Storage Is … Continue reading →

If the battery in your Mac notebook computer won’t charge, try one or more of these solutions: Reset the SMC: Reset the System Management Controller (SMC), which controls how your Mac manages power. Get your Mac serviced: If the battery … Continue reading →

A mini USB connector is a much smaller, five-pin version of a standard USB connector, with two crimped sides that give it a trapezoid shape. (Reach back to your memory of geometry class for that one!) These connectors are also … Continue reading →

9volt Batteries made their appearance on the World Stage when Portable Transistor Radios were introduced since Transistors needed a little more voltage than what a single cell could produce.So, your typical 9volt Battery is really a stack of individual cells, … Continue reading →

If your iPhone charger isn’t Apple-certified and it keeps breaking, that’s because it’s of cheap quality. Non-certified Apple chargers will contain flimsy materials, so even if you do take care of your charger it’s still most likely going to die … Continue reading →

Can I solder a USB cable? You can cut and splice your own universal serial bus, or USB, cables to meet the length and connector type that you require. The process requires only a wire cutter and electrical tape, though … Continue reading →

Laptop Battery Refresh Procedure Follow Connect the AC adapter and charge the battery fully. Fully discharge the battery (by running the unit) until the power LED goes off. Connect the AC adapter and charge the battery fully a second time. … Continue reading →

Can a laptop charger be fixed? Replacing the charge on an expensive new laptop seems like an unfair additional cost, luckily it’s one that can easily be avoided. So long as the cores are not damaged or exposed and the … Continue reading →
