Please ask yourself how anybody else (not you or somebody in your class or somebody with the same school book as you have) should be able to give a reasonable answer to that.
What would you have answered if I ask you if I shall turn left or right in the next road intersection to find the hospital? And I absolutely assume you can give me a reasonable (and correct) answer.
Go find a magic wizard. That's what it takes - and I'm not.
Exept from the magic wizard, there is one more thing you can do in order to get an apropriate answer. Just take the effort to upload the schematic. (i just proved to be a kind of wizard now since I actually was capable to write something back that make sense and also will be very helpful for you)
In the circuit which I have mentioned above.....two positive redundant sources are given through a single diode..and a negative supply directly to a circuit...I am not clear about the circuit as I have not seen the circuit and it has been been asked to me by a friend.
Members who recently joined might be spammers so their first few posts have their attachments stripped until they are reviewed by a moderator.
So the schematic attached by the nOOb might be stripped.
