How does a power adapter work?
In a power adaptor, there are several parts that convert AC power to DC power. The process starts with an electromagnetic coil acting as a transformer — rather than an inductor. After that, the lower voltage power converts to DC in a diode bridge rectifier. From there, a switch rapidly turns the power on and off, after which the power goes through a capacitor which evens the flow out before sending it out to the power cable.

How does a phone charger work?
If you are talking about a phone charger, they are designed to lower and change the outlets 120 volt A/C electricity to the 5 volt DC that your phone requires. Laptop chargers are similar but output higher DC voltages. The technology is called a switching power supply. The switching frequency is typically 20,000 cycles per second up to a million. Switching means that circuits are actually switching between off and on at these frequencies. Some people with extremely good hearing can her the vibrations cause by the switching. It's also possible your device is poorly made, the internal componets within the charger vibrates more than they would in a better high quality device.

How much frequency do you hear?
Most of the time, you don’t hear anything at all. The frequency range of human hearing is 20~20,000 Hz. This means that only when the vibrating ‘component’ completes a minimum of 20 cycles of vibration will you actually hear it. And the frequency range that humans are most sensitive to is between 2,000~5,000 Hz. The frequency of the vibration from electricity normally ranges between 50~60 Hz, which can be hard to identify. So, when there is interference from other noises, you won’t really notice it.

Why does my phone make noise?
The noise changes based on how much power is being consumed by your phone. When the phone is consuming power, the switch is 'on' more often. When the phone uses less or no power (unplugged), the switch (even if it operates at a supersonic frequency) may only be 'on' one out of every several hundred cycles, which creates an audible tone in the capacitor.
Why do transformers make noises?
It's normal for transformers and AC adapters to make these nosies. It comes from energy losses that are transformed into mechanical energy generating these sounds.
How does AC power work?
Basically AC power is first stepped down to a lower voltage (a bit above the output voltage), then converted to DC (rectified) with a diode bridge. Here's where the interesting part happens- a special regulator circuit rapidly switches the power on and off. The capacitor smooths this out, creating a constant voltage. This output voltage is continuously sampled by the switching regulator so it knows if the capacitor needs more 'on' or 'off' time.
Can a switchmode power supply catch fire?
It's a switch-mode power supply which is running at a frequency inside the human hearing range. If any part of it is burning out its a capacitor and it will not catch fire.
