hi,

Usually the hysterisis resistor is connected to one of the input terminals and the Output terminal of an Opamp.

To which input terminal should it be connected? Are the results same when it connected to positive or negative input terminal??

hi,
Hysteresis is 'positive feedback' ie: output to NI non inverting input, via a suitable resistor.

Look at this pdf.
