Hi everyone,

I need some help analyzing this simple circuit. I'm a mechanical engineer so I'm not too familiar with circuits. If you look at the attached pictures, you'll see the circuit I'm dealing with.

This circuit drives a piezoelectric at ultrasonic frequency (exact frequency not known). I recognize that there is a resistor (I'm not sure if its 100 ohms or 1 ohm, I'm having a little trouble actually telling which side is which), a capacitor which says 220 µF and 16V on it, and a small transformer (that says JJAXF 10-0005 on it).

There is also a silver oval with a 16,000 on it and I'm not sure what that part is, and there is a switch that turns the circuit on and off.

I believe this circuit is 0.8 Watts and it runs from a USB, so at about 5V and 500mA current.

Can anyone help to:

#1. Explain each part of this circuit and

#2. Explain the actual function of each? For example, what would happen if I leave out the capacitor? Are each of these pieces required to have a functional piezoelectric?

Your help would be greatly appreciated!

Btw: The function of this piezoelectric is to atomize water. This particular circuit doesn't actually work too well.
