Question B-004-002-006

If alternating current is applied to the anode of a diode, what would you expect to see at the cathode?

Correct Answer

Pulsating direct current

Explanation

Assuming the cathode is connected to the load, the diode conducts only on the positive half-cycle of the AC input (anode positive relative to cathode), resulting in half-wave pulsating DC at the output.
