🔍 Key Concepts

• Rectification: how AC is converted to pulsating DC using diodes • How a center-tapped transformer with two diodes behaves over one full AC cycle • Relationship between number of pulses per cycle and half-wave vs full-wave rectification

💭 Think About

• Look at section B and trace current flow during the positive half-cycle from the upper end of the transformer secondary through one diode to TP3. • Then trace current flow during the negative half-cycle from the lower end of the transformer secondary through the other diode to TP3. Does current still flow in the same direction at TP3 or does it stop? • Compare the resulting waveform at TP3 with the sketches marked E, F, H, I. How many pulses appear for each full AC cycle?

✅ Before You Answer

• Verify how many diodes are in section B and how they are connected to the center-tapped secondary of T1. • Check whether both halves of the AC waveform contribute to output at TP3, or only one half. • Confirm that the term you choose (half, quarter, full, or short wave) correctly matches the number of DC pulses per AC cycle created by this configuration.
