What's the normal low-load working temperature for an SMPS transformer...
Hi! I have question about high frequency transformers inside switch mode power supplies (SMPS). Is it normal for them to become hot under no load or low load? For example if power supply is rated for 144A at 13.8V and I only pull from it 2A at 9.6V, it normal that transformer becomes about 50C just

What is voltage when running current through copper plats?
Hey everyone, I'm hoping that you guys will be able to help me with some calculations. I was on YouTube and came across this: I then began to wonder if I could make a solenoid using bitter disk as in the video, granted no where near as powerful. I would say 1 tesla using an iron core. After some di
