Alternating current (AC) is a type of electricity that changes both in size and direction over time.Alternating current (AC) is triggered by an alternating current generator. in the power generation process, many pairs of magnetic poles are evenly distributed in a circle at a certain angle. In this way, each coil is cut into the magnetic line during the power generation process, because there are many pairs of magnetic poles, the voltage and current produced by the split of the magnetic lines pr

All are DC. HDC is the original DC handle. The first parameter of many APIS is an HDC type. For exampleHDC hDC =: GetDC (m_hWnd);: MoveToEx (hDC, 0,100, NULL);: LineTo (hDC,);: ReleaseDC (m_hWnd, hDC );In MFC, a CDC is added to encapsulate an API as a class for operation. So in MFCCDC dc = GetDC (); dc. MoveTo (0, 0);

horizon, it is generally safe to observe through the viewfinder. The higher the sun is in the air, the more dangerous it is to directly observe the sun, especially with a long distance lens. For safety, you can stick a piece of running or black film (a 35mm-long small film is ideal) to the viewfinder, so that you can observe the sun and determine the best picture. The breadth and abundance of shadows. With the increasing popularity of digital technology, digital cameras (

The constant change in size and direction is called pulsating DC power.DC waveform should be straight, pulsating DC waveform although only positive half-week, but not continuous, this is the pulsating DC pulse DC current is the direction of the constant, but the size of the current has a cyclical change. For example, a

The DC, the device context, is a data structure within GDI, and a DC is associated with a particular display device, such as a printer, screen, and so on. If we can get the DC's handle then we can write and paint on the display device. There is a HDC attribute in form or PictureBox, and that's the thing, but how is there a memory DC? This is a

Electronic Circuits Require DC power supply to provide energy. Because the battery cost is high, it is generally only used in low-power portable instruments. Here we will discuss how to convert an AC power supply to a DC regulated power supply. The general DC power supply consists of the following parts: the rectification circuit is to convert the Power Frequency

Container technology is currently a very popular technology, especially driven by the use of docker as a container engine, so that containers are lightweight, portable, and self-contained, isolation has taken a new step. Currently, when talking about Dev/OPS, Ci/CD rarely bypasses docker. Azure launched the container service ACS last year. It is well received for its comprehensive compatibility, openness, and comprehensive orchestration tool (DC/OS, k

DC (device context device description table)DC is an inclusive device (physical output device, such as a display, and device driver)Program) Structure of information. In windows, all graphic operations are performed using DC. For example, a teacher asks a student to draw a Forest image. Some students use a sketch, and some students use Watercolor Painting, some

The Device Description table (DC) is a data structure in Windows that contains all the description fields that GDI needs about the display interface, including connected physical devices and various state information. Graphics display function is done by the graphics card, you want to use the graphics display graphics function to complete your graphics output, how to do, give you a piece of hardware to use it? OK, now the manufacturer gives you a dr

When writing a dialog box-based MFC program, you need to move the image with the mouse. I checked a lot of information on the Internet and found that most of them are implemented based on cview. there are few examples of cdialog-based image dragging, and the examples are incomplete. here, I have posted the complete image dragging code on the Internet and compiled by myself over the past few days, hoping to help you. First, I added an image control idc_static, and then dragged the image in this c

in GDI, the DC (Device context) is a very important concept. Some books translate DC into a device description table (author Charles Petzold of Windows Programming version fifth), and some books translate DC into device contexts. exactly what is DC. It may be easier to understand in real-world examples. If you l

Short-circuit protection is an obvious requirement for a power supply, especially when it load connects to a cable that ' s Subject to damage. Many modern Power-converter ICs include some means of protection, such as thermal shutdown, against the overload condition , but, in some cases, the built-in protection could be inadequate.figure 1shows a step-down DC/converter for both VI Deocameras installed on a remotely controlled vehicle. Because the vehic

It is the front of many inverter circuits, which can carry out the pressure, then what is his concrete realization idea? What are the impact variables? What are the characteristics? What is the essence? These should be questions that are of interest to beginners, including me. According to some of our previous impressions, Buck can be distributed by resistive load, while a transformer can achieve a lifting pressure. The transformer utilizes the inductor, the energy-transforming device. In fact,
