Inverting and Non inverting Amp Qns - Electronic Circuits Projects Diagrams Free

Hi guys,

I actually did an experiement on using a opamp 741 chip.
I noticed I have different V out results for inverting and non inverting amplifier though both I set to have the same gain. I even supplied the same input voltages 1V in both cases. I got Vout 1.8V for non inverting and 1.82V for inverting amp. Why is there a minor variation? Is this suppose to be normal?

Thanks in advance

Try giving circuits and values, I'm presuming you are aware that the gain formula is slightly different for the two modes?.
