Hi everyone,
I accidentally plugged a 15v dc power supply into a small analog circuit that required 9v. This made it stop working, I was wondering if doing this would just mess up the first component in the circuit? or does it wreck all the components?
thanks,
Kyle

 

It depends on the circuit.

What circuit/device is it?. If possible post a picture of the PCB(s), the model, manufacturer, as much information as possible.
