Answer:
a) The forward voltage is 0.23 V
b) The current that flows
Explanation:
The forward voltage is the minimum voltage that must be applied to a diode before it starts to conduct. The equation is given by:
a) At what forward voltage does a diode conduct a current equal to 10,000 Is ? In terms of Is
Where:
Id is the diode current = 10000Is,
Vd is the forward voltage at which the diode begins to conduct,
Is is the saturation current.
Dividing through by Is,
Taking the natural logarithm of both sides,
multiplying through by 0.025
= 0.23 V
The forward voltage does a diode conduct a current equal to 10,000 Is is 0.23 V
b) what current flows in the same diode when its forward voltage is 0.7 V?
