| 1. | The voltage across R 2 forward biases the emitter junction.
|
| 2. | The latter dominates under forward bias while the former dominates under reverse bias.
|
| 3. | Forward bias ( positive to positive ), reverse bias ( negative to negative ).
|
| 4. | The forward bias causes a force on the electrons pushing them from the N side toward the P side.
|
| 5. | Note that, in general, 3 volts P to N forward bias would be sufficient to burn out most diodes.
|
| 6. | There is also a recovery concern where the current will not decrease immediately when it is switched from forward bias to reverse bias.
|
| 7. | I agree that 3 volts of forward bias might fry the device . talk ) 16 : 06, 2 March 2012 ( UTC)
|
| 8. | For even rather small " forward bias " voltages the exponential is very large, since the thermal voltage is very small in comparison.
|
| 9. | The Shockley diode equation doesn't describe the " leveling off " of the I V curve at high forward bias due to internal resistance.
|
| 10. | Photoelectric diode in " forward bias " configuration, used for measuring the work function " W " e of the illuminated emitter.
