Are you considering the V' as output?

is it potential across R??

It is certainly the potential across R.

Should it look like a square output (in the same phase) as well????

Well, I don't know. Anyone who sees the problem would say that only. But It doesn't satisfies the mind. Kindly present the logic please (if any)

Well.. i dont agree with the above post..

I ll post something to give u the feel of the problem after a few mins.. a bit busy now...

Look it is a problem of transients... we are charging and discharging the C periodically....
Thus accordingly, the R will have some potential differential across it..

another thing to realise is the output wave form is exponential and not square...

I guess this basic background (in "somewhat" layman language) is enough?

Need something more? Tell me.. i ll give more hint...

Should It look like this then :?

Yes....shubhomoy is probably right...my fault...
The graph is exponential...but the amplitude is less than the supply voltage as there is going to be a drop across the capacitor equal to magnitude I*XC.

So final answer please?
