Is it possible to form a voltage source of 7v by connecting 10 diodes in series & taking the voltage across it..? if am using USB port of pc to get 5v wil it affect PC if there is any short circuit or problem in the circuit to which am connecting..? pls help out... Thanks in advance...:)

Your question is really incomplete and/or doesn't make sense.

No it is not possible to form a voltage source with diodes in series and no other components. A battery is a voltage source. A diode is not.

You could put some photodiodes together in series and shine a light on them, that would create a voltage source but of somewhat unpredictable output.

What do you need the 7V for and what's it have to do with a USB I/O port?
