We already know that in a DC Series motor the field winding has very less resistance than a DC Shunt Motor as the field is connected in series with the Armature Winding. So if we give AC supply on a … Continue reading →

AC/DC converters are electrical circuits that transform alternating current (AC) input into direct current (DC) output. AC/DC Converters are also called “rectifiers”; they convert the input AC voltage to variable DC voltage, then optimize it through a filter to obtain … Continue reading →

The voltage dropped by a resistor is given by Ohm’s Law: V = I R. So if you know exactly how much current your device will draw, you could choose a resistor to drop exactly 7.5 V, and leave 4.5 … Continue reading →

A switching AC/DC power supply enables the creation of more efficient power converters, which no longer dissipate the excess power. AC/DC power supplies that are designed using switching power converters are called switched-mode power supplies. What is a switching AC … Continue reading →

PCIe cables connect directly from the Power Supply Unit to the installed PCIe Expansion Card; Graphics Card. A typical PCIe x16 slot on which you install the graphics card supplies 75 watts of power. What does the PCIe plug into? … Continue reading →

How to Connect Power Button to Motherboard Locate the Front Panel Header. As mentioned earlier, the pins for the power switch can be found on the motherboard Front Panel Header. Determine the PINs Intended for Power On Switch. Connect the … Continue reading →

To get a stable voltage out of it, you want a voltage regulator. Voltage regulators come in two flavors, linear and switching. If you want the output voltage of the regulator to ever be higher than the battery voltage, you … Continue reading →

What is a plug in called on a cord? Pin and Sleeve – A receptacle, connector or plug that has round pins or sleeve-type contacts. Plug – Also called an “attachment plug,” it is the cable mount portion of an … Continue reading →

If the input voltage is higher than the normal, it will lead to electrical burned and may cause serious consequences such as fire. If the input voltage is below rated, the electrical appliance can’t work normally or simply failed to … Continue reading →

Ways to Revive a Dead Car Battery Jumpstart: Jumper cables and a second battery, battery booster, or second vehicle might be enough to jumpstart the vehicle. Distilled Water: If the electrolyte level is low, adding distilled water might be enough … Continue reading →

A laptop doesn’t have a power supply inside the case that converts power. Instead, it has an AC adapter that works same as power supply does and it provides the power to the laptop. What is the power supply on … Continue reading →

Plug adapters (or travel adapters) Travel adapters simply allow a device from one country to be plugged into the wall outlet of another country. However, they do not convert electricity. The plug of a Continental European appliance will not fit … Continue reading →
