Can you please help me to find a short answer for the following question in full and half wave rectifier 

1. Why will Vp not be exactly equal to the peak value of the supply? 2. How much is the difference between the peak value of the source and the peak value of half wave and full wave ? 3. How much is the difference between the measured and calculated mean (dc) voltage? and why this difference? 4. How much is the difference between the measured and calculated RMS voltage ? and why this difference ? 5. Draw the voltage a cross the diode in the half wave rectifier ? 6. plot Vin and Vout for full and half wave ? Comment your results
