It's the handle of a water kettle. Behind the circuit board is nothing. There is also no other circuit board in the kettle. Is the yellow thing the beeper? Thanks for any help ๐

Is the capacitor an x2 cap for voltage surges? Looks like it. The rest is just normal stuff. Not my field, been out of school for years and am an idiot. That being said I'm curious: what's the inductor by the Emi suppression capacitor for in this circuit? Is it just to form a tank circuit to heat the kettle more efficiently?
cannot say.
idk, not familiar with those things. the kettle can has 5 modes of temperatures: 60โ100 ยฐC. Its really nice, just insanely loud. More pictures if case it gives more info, sorry for the bad quality, hope its readable
Top is a relay, bottom is a capacitor. Thanks! The sound you're hearing is probably from a piezo buzzer like some one else mentioned. I wish I was home so I could send you a picture of one. They can be really loud!
Here's what those buzzers can sometimes look like:
They just make sound to indicate the state of things when used as part of a circuit. Like your kettle being finished boiling water.
