what i mean is that; i want to vary the value of R load and plot the power dissipated to load resistance. hence be able to see the maximum power dissipated to the load.

Do you mean the peak power or the average power?
The peak power can be had the way Hero told you about.
If you need the average power you would integrate i(t)*e(t)
over all time, which is the same as using an RC filter on i(t)*e(t)
where the time constant is large compared to the change in
the amplitude of the waveform.
