Half Wave Rectifier
 Aim: To implement a Half-Wave Rectifier circuit with and without a capacitive filter and to calculate its ripple factor
Requirement:
Function Generator                             1Digital Multimeter                              1CRO (20 MHz dual)                           1Diode 1N4007                                    1Resistor 1 K                                        1Capacitor                                             1Breadboard                                         1Circuit Diagram: Activity 1: Without Capacitive Filter
Procedure:
1. Connect the circuit as shown in circuit diagram Fig.5.1
2. Apply the input sine wave of magnitude 5V(P-P) and frequency 1kHz to the rectifier      and observe the output waveform
3. Sketch the output waveform as observed in the CRO
4. Measure the output dc voltage(V_dc) and the peak output ac voltage(V_m) using the CRO and the digital
    multimeter .
5. Calculate the ripple factor using the formula given bellowγ = V_rms / V_dc
Where V_rms is the rms value of the ac component =V_m / 2

Activity 2: With Capacitive Filter
Procedure:
Procedure:
1. Connect the capacitor across the load
2. Repeat step 2 to 5 of Activity 1.
                                3. Also calculate the ripple factor using the formula and compare the result.
                                                                          
                                                                                         γ = V_rms / V_dc
 4. Sketch the input/output waveform .Conclusion:
