A failure in the functioning of your car’s USB port can usually be traced back to a shortcoming in the hardware or software. Despite how powerful and useful they are, they’re more prone to particles getting inside because they’re open. … Continue reading →

cycloconverter. A cycloconverter is a transformer that converts AC power of one frequency to another. What is an AC to AC converter called? A power inverter, inverter or invertor is a power electronic device or circuitry that changes direct current … Continue reading →

How does a DC transformer work? The DC-DC converter input is switched by solid state switches (DIACs) to produce a square wave across the transformer primary winding and then the transformer secondary winding produces the required output voltage, this is … Continue reading →

The most significant difference is in design. While generators feature a stationary field in which the armature rotates to produce electromagnetic induction, an alternator’s entire magnetic field turns with its conductors remaining stationary. Generators are capable of both AC and … Continue reading →

Hard or Soft Wired Soft wiring is more environmentally friendly and cost effective making it easier to reuse workstations and wiring whilst reducing waste and redundant power and data. Hard wired power and data is more permanent but can be … Continue reading →

What is the end of a plug in called? A connector is the unique end of a plug, jack, or the edge of a card that connects to a port. For example, all desktop computer expansion cards have a connector … Continue reading →

Conditions such as heat, cold, dust and excessive humidity all can damage and lessen the performance of a computer. External and internal temperature especially cause fluctuations of performance, although a computer is more vulnerable to heat than to cold. Does … Continue reading →

The sizes and shapes of connectors do not consistently correspond to the same power specifications across manufacturers and models. Two connectors from different manufacturers with different sizes could potentially be attached to power supplies with the same voltage and current. … Continue reading →

In regulated power supplies, a circuit continually samples a portion of the output voltage and adjusts the system to keep the output voltage at the required value. In many cases, additional circuitry is included to provide current or voltage limits, … Continue reading →

The power supply transformer raises or lowers the voltage as needed. Most devices require stepped down voltage from standard AC outlets, which output 100 to 240 volts, to a much lower amount. Some transformers, however, will step up the voltage … Continue reading →

Since the case isn’t metal, you won’t easily touch metal. However, the manufacturer used a three prong plug implying you can get a shock if an overvoltage event occurs and you touch the wrong thing. Short answer, nothing stops you … Continue reading →

Four ways to kill a laptop in 10 seconds or less Keep drinks nearby. Everyone at least knows of someone who has spilled soda on a keyboard. Drop it on a hard surface. One of the most dangerous things about … Continue reading →

Leaving your computer turned on 24/7 can remove a few of the known stress events that lead to component failure, including the in-rush of current that can damage some devices, voltage swings, and surges that occur when turning a computer … Continue reading →
