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.
