Introduction It is possible to predict the performance of a transformer at various levels of load by knowing all the equivalent circuit parameters. These circuit parameters are supplied in terms Open Circuit (OC) and Short Circuit (SC) test data of a transformer. Without actually loading the transformer, these two assessed tests give the test results, which are used to determine the equivalent circuit parameters. By these parameters, we can easily predetermine the efficiency and regulation of the transformer at any power factor condition as well as at any load condition....

Today, we are going to discuss Oxy Acetylene or Oxyfuel welding in detail. This is also one of the popular welding methods that is quite popular for a wide range of applications. One of the biggest benefits of Oxyfuel welding is that it does not require a controlled pressure or any kind of filler material. On top of that, this is a versatile process that has many other applications apart from welding....

Display and Processor Panasonic P81 sports a 5.5 inch IPS HD screen as compared to HP Slate 6 which flaunts a 6 inch IPS HD display. Both the phones offer the same resolution but the pixel density of HP Slate 6 is marginally lower than that of Panasonic P81. Panasonic P81 leads the line here with a resolution of 780 x 1280 and a pixel density of 267 ppi. Panasonic P81 packs MediaTek MT692 octa-core SoC clocked at 1....

But due to the large amounts of forward current and revere bias voltage, small signal diodes may be overheated and get damaged in the process of rectification. In such cases, Power Semiconductor Diodes are used to overcome the excess currents and voltages. A Power Semiconductor Diode is a crystalline semiconductor device, also known as Power Diode, used mainly for the purpose of rectification. This type of rectification process is mostly seen in all power supplies of modern-day electronic and electrical apparatus....

Brightness: While buying any sort of light, you would want it to be as bright as possible. Thus, make sure to check the brightness rating of your LED shop lights as a 10000 or 12000 lumen light is going to be much brighter than a 5000 or 6000 lumens one. Color Temperature: Other than the brightness of your LED shop lights, you should also check the color temperature to get an idea of the color of the light that it produces....

Type of Plug: There are 2 different types of plugs available that are male and female type RV plugs. Keep in mind that both of these options are completely different from one another. You might need either or both, depending on your power source. Amperage Rating: Similar to all electronic adaptors and power cords, the RV plugs also have a limitation of amperage, and it could not be used for higher power application compared to its amperage rating....

Capacity: If you wish to mix a lot of concrete at once, then you should get a concrete mixture machine with a high capacity. It includes options like 4 cubic feet or 2 cubic feet mixture machines with the former rating offering the higher capacity. Motor Power: The motor power offered by a concrete mixture machine is also quite important. This is due to the reason that a ¾ HP electric motor will mix different things better than a smaller ⅓ HP electric motor....

But, just like a home, there are various connections needed for an RV when you go to an RV park. This also includes connecting to a sewer outlet using something like the best RV sewer hoses stated down below that offer the following features: Length: Just like any other hose or pipe, your RV sewer hose should also be decently long so that you can easily connect your RV’s sewage discharge port to a sewer outlet....

These include the power source, welding parameters (voltage or ampere), and the nature of shielding gas. Electrode surface, Chemistry, diameter, and tip-to-work distance also play a key role in the determination of transfer mode. Taking all the parameters into a note, four welding transfer parameters have their characteristics and applications. The three transfer modes, including Short Circuiting, Globular, and Spray transfer mode can be done by the constant voltage, whereas the fourth and the last Pulse spray transfer mode require an advanced power source....

The traditional green color coating that you see on the PCBs is the solder mask. Some PCBs also use different colored solder masks. When the board reacts with atmospheric air, it loses its chemical properties and also starts to rust. This is called oxidation. The solder mask prevents the board from reacting with oxygen. Besides, contamination such as dust and debris may get settled on the board which can lead to electrical shorts....
