I am using a normal 9v battery connector to power a simple breadboarded 741 IC square wave oscillator circuit. This is my very first circuit, and I immediately noticed that it did not work unless I put the leads on the battery backwards...? This must be some simple silly thing I did, but I would really like some help on this... Thanks!
