K.C.S.E Physics Q & A - MODEL 2019PP2QN09

Figure 4 shows the input and output signals on a CRO screen when two diodes are used during a full wave rectification.

Explain how the two diodes rectify the input signal.

answers

During the first half cycle of the input signal, current flows in the first diode
During the second half cycle of the input signal, current flows in the second diode
When the current through the two diodes are combined a fully rectified wave signal is obtained as the output signal.
