I have been winding my own transformers for hobby use for over 40 years (5W to 800W). I think that this video is great and you have explained it in a very simple way. Perhaps you may like to add that the core area also determines the maximum power handling capacity of a transformer. I always use inches, but as a rule of thumb, converted to cm, it is in the region of about 5x the core cross sectional area in square cm for power levels from 10 to 100 Watts. For example 2cm x 3cm x 5 = 30 Watts. BR Harry
Little extra data - 1 square inch area is good for up to 31 watts. 2 square inches will give up to 122 Watts. In inches: Sqr (A * 5.6) gives you the exact power handling. I will leave that to you to convert to cm ;-)
calculating turns per volt,what this formula means and how to use it,please explain,=1/4.44 x10-4 x 18 x 1.3 x 50 ,where this numbers come from,if I know I can use the formula...thanks
If you do not know the “quality” of flux of your transformer core you may Pick any value between 100000 and 60000 depending on again what quality your transformer core is
6.25 constant used for 60hz cycle while 7.5 constant is used for 50hz cycle with 60,000 flux density per inch squared and also the core area is measured in inches.... how about the CORE capacity or CORE power, can you Give a FormuLa ?? I assure there is a formula for calculating CORE POWeR capacty... thnx....
Totally incomplete video. with music and without voice no one can understand this video. For example what is "E" not understood, where to come and what is(10⁸ ) not understood. After watch this video I figure out the result thatActually the uploader of this video only collect some transformer pictures from internet and combine them .he is also not to know that what he is making.
