🤷 MY REVIEW:
Video How Does a Transformer Works? is one of my best videos. I worked on it for about 4 months, it is made in 3D animation, even cooling air around an electric transformer and oil inside a transformer. Honestly, I think that I covered all the important things about transformers and make an explanation in an easy and understandable way. So, please, I expect any feedback from you, good or bad.
