PROCEDURES :
1.
Construct the half-wave rectifier circuit as shown.
2.
Monitor the input voltage using the oscilloscope.
Adjust the oscilloscope to show at least two complete cycles of the input
signal.
Draw the input waveform in Graph 1 and measure the peak-to-peak value.
Record this in Table 1. Convert this value into RMS value using the

In drawing the waveform in Graph 1, show only two cycles of
the signal being measured.
NOTE :
5.
Monitor the output voltage and adjust the oscilloscope to show at least two
complete cycles of the signal.
Draw the output waveform in Graph 2 and measure the peak value of the
voltage. Record this in Table 1.
Reverse the diode in the circuit and observe the effect on the output
waveform. Return D, to its original orientation.
Connect the probe of the oscilloscope across the diode placing the ground
lead at the cathode of D1.
Draw the waveform in Graph 3 and measure the peak value of the
voltage. Record this in Table 1. Ce
