The drop across the feedback resistor is independent of the resistor to ground. | |

May 8, 2017 at 16:59 | comment | added | Moeen Ahmed | Oh I got it. When they say a source resistance of 5k, they do not mean the resistor on the inverting lead/wire. They mean 5k is the resistance of a source voltage attached to the non-inverting lead/wire. The resistance attached to the inverting lead can be calculated using the formula Vo/Vi=1+(R2/R1), where R1 is the unknown resistance on the inverting lead. The wording of this question is very terrible. | |
