remaining low voltage pin is the collector C. Another method is to use HFE block to judge. After determining the base and tube of the transistor, the base of the transistor is inserted into the LO value measurement hole according to the base position and the tube type, the other two pins are inserted into any two of the remaining three measuring holes, observe the size of the data on the display, find the

and the load are connected in series, 3 (b), can also filter out the AC components in the ripple.(3) L, C filterA filter circuit consisting of 1 inductors and a capacitor is called an L-shape because it resembles an inverted letter "L", as shown in Figure 3 (c). A filter circuit with 1 inductors and 2 capacitors because the letter "π" is called the π type, see Figure 3 (D), which is a better filter circuit.(4) RC filterThe cost of the inductor is high, the volume is large, so in the current is

Note: Since the topic has not been added to the question bank, so I give the code does not guarantee AC, but for the test case to give the basic idea of the problem is correct.

This is because Norton 2002 's previous version of Norton Antivirus is incompatible with Windows XP, and this incompatibility is due to the NTLDR of the new operating system, N

Linear regulator based on op ampLinear regulator based on op ampWhy DIY?There are two reasons, the first is the market on the three-terminal regulator does not meet the requirements, either performance is not good, or not enough power.Second, the market also has a single show, excellent performance of the regulator, but they are expensive,For example, Ling Linear Technology's lt1581,13 dollars/piece, buy a bunch of components. Or they are uniquely packaged and cannot be easily interchanged with

Photoelectric Coupler, usually referred to as photocoupler. The basic principle is to transmit electrical signals using light as a media. In some special application scenarios, the input/output end is required to achieve electrical isolation, so that traditional electronic devices cannot be used to

controls the power supply of the entire system. When the system has not been measured for more than 10 s, the power supply system of the entire system will be closed, in this way, the system consumes almost 0mA of the current (the Power Management Switch MOS tube consumes a small amount of static current ). Based on the above two factors, the system power-off management solution is more energy-saving, and is more suitable for laser range finder hosts

Faulty model: Great Wall C-I5271 type display; Fault Cause: Lightning strikes; Fault symptom: no display. The user reported that when the machine was struck by lightning, it made a "bang" sound. Analysis and maintenance: the power fuse (f901/3.15a) has been burned out and is black inside the casing. This indicates that the power supply has a serious short circuit fault. Test the Power Supply Adjustment tube drain pole (d) to ground resistance

The adjustment tube of the linear power supply is working in a magnified state, so the heat is generated and the efficiency is low (about 35%). A large heat sink is required, and a large power frequency transformer is also required, the transformer will be larger when multiple voltage outputs are to be made.The adjustment tube of the switch power supply is working in saturation and cutoff state, so it has a
