How Does Voltage Drop Occur in Diodes Despite Forward Bias?

Click For Summary
SUMMARY

The discussion centers on the phenomenon of voltage drop in diodes under forward bias conditions. Despite the depletion region being absent in forward bias, a voltage drop of approximately 0.7 volts is observed. This voltage drop is influenced by both the current flowing through the diode and the temperature, as confirmed by the referenced thread on Physics Forums. Understanding these principles is crucial for grasping diode behavior in electronic circuits.

PREREQUISITES
  • Understanding of semiconductor physics
  • Knowledge of diode characteristics and behavior
  • Familiarity with forward bias conditions in diodes
  • Basic concepts of current and temperature effects on electronic components
NEXT STEPS
  • Research the relationship between current and voltage drop in diodes
  • Explore the effects of temperature on diode performance
  • Learn about the depletion region in semiconductor devices
  • Investigate transistor amplifier configurations and their characteristics
USEFUL FOR

Electronics students, electrical engineers, and hobbyists interested in understanding diode behavior and its implications in circuit design.

the depletion region is resposible for voltage drop
all that is fine
but in forward bias there is no depletion region hence there can be no voltage drop
but it is mentioned in my book that the voltage will drop by .7 volt
how come this can happen


also i have many doubts in transistor amplifiers
waiting for reply's
