TASK 2 : Measure the input AC voltage and output AC voltage and DC voltage by CRO
1 Connect the input and output terminals of the rectifier to the probes of CRO.
2 Measure the peak voltage AC input voltage and measure the time period of cycle by CRO.
3 Measure the peak value of output DC voltage by CRO and note it.
Sl.No Input AC peak voltage Output DC peak voltage Time period T (ms)
TASK 3 : Calculate the Vrms , Vdc, and ripple factor from the measured peak value
With filter: Ripple factor, r = 1/ (2√3 f C RL) for Half Wave rectifier and 1/ (4√3 f C RL) for Full Wave
