Abstract
Abstract: A half wave rectifier utilizes only one half cycle of the A.C signal. Since the circuit can not be 100% D.C the output contains ripple. These A.C components when fed to a transformer may give an A.C voltage at the transformer output. But this voltage varies with load at the output i.e. it depends on whether the load is linear (resistor), non linear (diode), capacitive or inductive etc. Also the output voltage varies if a capacitor is connected in parallel to the resistance which is connected in series with the half wave rectifier. An incandescent lamp having a tungsten filament is used to control current. An amplifier constructed using a single transistor was also used to study the relationship between the no load voltage of the transformer and the full load voltage. At 50Hz the ripple components in a half wave rectifier are just enough to give about 6V amplified output when a 10W lamp is used to control D.C current in the circuit (later explained in the diagram). The power consumption in the circuit considering stray losses is about 15W which is fairly small.
