Wanna get your advice regarding powering up Arduino Uno using AC/DC Adapter to the barrel jack.

The first adapter I use couldn't work and the shop which I bought it from said the adapter was short circuit-ed.

Out of goodwill, she replace it for free and I tested it out again. The first few tries it worked perfectly fine but stopped working (suspected short-circuited again).

The adapter output is DV9V - 2A.

The circuit consists of 2 ultrasonic sensor and 1 buzzer.

I am quite sure the Arduino circuit does not draw more than 2A of current.

Any idea what's the issue? Thanks!

EDIT -

I've uploaded a photo of the schematic done using Tinkercad. I am using a different breadboard thus the configuration as shown.
