This video shows how to identify the pins 2n3055 transistor by two ways: 1.By using the datasheet of the transistor. 2.By using the multimeter & the datasheet. Although the datasheet provides the correct information to identify the pins of this transistor majority of the people find it very difficult to extract this information directly from the data sheet as identifying the pins from the transistor depends upon the physical dimensions of the transistor. Although the transistor layout looks symmetrical it is not ,so measuring or judging by the eye is difficult as the difference is only a few millimeters. In this video with the aid of a multimeter we determine the pins of this transistor very precisely. The datasheet clearly states  that the metal casing  of the transistor is the collector so the problem is actually determining the base and the emitter of the transistor. For the process we start by putting the multimeter to the diode mode and then connecting the probes to

Comments in C++ Programming Comments are used mainly to describe the code. Comments are ignored by the compiler. There are two types of comments: Single line comments. Multi-line comments. Single line comments start with two forward slashes // Comments are just to describe the code,they are never executed. Multi-line comments: This type of comments are used to comment out multiple lines. This type is better for giving a detail description of how the code functions. Multi line comments start with /* and end with */ In between the content is added. Multi line comments span multiple lines. You can even nest comments one type of comment inside another . Adding comments in the code makes no difference to The results of the code is as the comments have no influence on the code. Adding comments is a good practice as it facilitates a clear understanding of the code for you and others as well. Example: /* Hello user this Is an example of multi line commenting*/

How To Make a 0-12V Variable Power Supply In Sinhala | Part 02 Expanding the setup to a 0-12V variable power supply. We have already completed the 12V fixed powersupply tutorial vide so if you havent watched it first watch it and continue. By now we have completed the project upto a 12V fixed power supply as our next step we are to make the power supply variable. Additional Components Required: D400 x1 2N3055 x1 100kO variable resistor 1kO  Determining the pins of the d400 transistor is very straight forward but it can be tricky in the case of 2n3055. Refer the pdf for the pin configuration of the D400 transistor: 2N3055 : According to the data sheet the metal casing is the collector of the transistor. The problem is identifying the base and the emitter of the transistor. Steps: Put the multimeter to the diode mode. Connect the probes of the multimeter to the two leads of the transistor. If there is a reading on the multimeter then the positive probe is the ba
