I'm freaking out over a high pitch noise (very faint) coming from my power supply and wanted to clarify some things so that I can be sure i'm safe.
I have a 12V DC power supply (1A) that has 2 components connected in parallel. The circuit works perfectly but I'm pretty certain that this circuit is trying draw more current than power supply can provide.
What happens in this instance?

What happens in this instance?
- Does the power supply just continue working while limiting current draw to 1A?
- Is there any danger either to the power supply or components in this case?
- Why am I hearing this slight screeching noise? Another thing to note is that shaking the power supply you can hear some sort of small piece inside moving around.
