Can some one explain this problem to me. Im trying to see how to understand electronics in terms of real life and not just book problems. I understand the basics of what an inductor does but how can i apply the basics to this problem which is the following:
There is a BUZZ in your phone, which seems to go away when the battery is fully charged. You suspect the noise comes from an inductor in the phone's power supply. You open the phone, look at the power supply and see a ferrite core inductor: but some of the windings do not appear to be epoxied into place. Explain how this might cause the noise.
