hi i am working on a project and i want to test the power factor of different loads in a circuit so can anyone help me that how to find power factor of a circuit or a load in pspice ?

It's been a while since I've played with the math functions, but you should be able to implement math functions that integrate the real power pretty easily and those would work for any waveform. You get the apparent power by first measuring the RMS current and voltage and then multiplying them together. Then use the definition of power factor as being the ratio between real power and apparent power.
