Study Notes

Semiconductor Junction

When a P-type semiconductor and an N-type semiconductor are joined together, a p-n junction is formed.

N-Type Semiconductor

The majority charge carriers in an N-type semiconductor are electrons.

P-N Junction Diode

In a forward-biased p-n junction diode, the depletion region is narrowed, allowing current to flow easily.
The circuit symbol for a forward-biased diode is an arrow pointing in the direction of conventional current flow (from anode to cathode).

Half Wave Rectifier

The main function of a half wave rectifier is to convert Alternating Current (AC) to Direct Current (DC) by allowing only one half of the AC waveform to pass through.
