A voltage divider is a circuit that produces an output voltage that is proportional to the input voltage. One typical configuration consists of a pair of resistors in series from the input voltage to ground, with the output voltage taken from the junction of the resistors. As an example: two equal-valued resistors will give an output voltage that is 50% of the input voltage.

How to calculate the node voltages for this circuit using the voltage divider rule
First off, you incorrectly reduced the combination of 1k||3k to 2.35k. This is incorrect on it's face since whenever you have resistors in parallel, the combined resistance is less than either resista …

Reference voltage changes when connected to inverting input of op amp comparator
I don't see any negative feedback on the op-amp. You are exceeding the differential input voltage of the op-amp. According to page 2 of its datasheet the maximum is 0.5V and it has protection diodes s …
