thanks my friend for answering. i want to know how i can measure ripple voltage in pspice. idont know how i can in option of pspice?It is trivial to do, but you have to make some assumptions:
What is the A.C. voltage source peak-to-peak voltage?
What is its frequency?
What is its internal source resistance? (or is it "ideal")?
What are the attributes of the diode? (or is it "ideal"?
Here it is with a 3vpp 50Hz ideal source with an ideal Silicon diode.

Notice that the first current pulse is subtly different the subsequent ones... Notice that LTSpice is smart enough to plot the power in any component, in this case, the 10k resistor.
You owe it to yourself to try this free program.
