The junction diode in the following circuit requires a minimum current of `1 mA` to be above the knee point `(0.7 V)` of its `I-V` characterstic curve. The voltage across the diode is independent of current above the knee point. If `V_(B)=5 V`, then the maximum value of `R` so that the voltage is above the knee point, will be

Assume that the silicon diode in the circui shown in fig. requires a minimum current of 1mA to be above the knee point (0.7V) of its I-V characteristics. Aslo assume that the voltage across the diode is independent of current above the knee point. If V_(B)=5 V, what should be the maximum value of R so that the voltage is above the knee point?

Assume that the silicon diode in the given circuit requires a minimum current of 1 mA to be above the (knee-point voltage = 0.7 V) of its I-V characteristics. Assuming that the voltage across the diode is independent of current above the knee-point, find the maximum value of R so that the voltage is above the knee-point if V_(B) = 5A . Also find the value of R to establish a current of 5 mA in the circuit for the since voltage.

Assume that the silicon diode in the circui shown in fig. requires a minimum current of 1mA to be above the knee point (0.7V) of its I-V characteristics. Aslo assume that the voltage across the diode is independent of current above the knee point. If R=1kOmega , what is the minimum voltage V_(B) required to keep the diode above the knee point?

Assume that the silicon diode in the circui shown in fig. requires a minimum current of 1mA to be above the knee point (0.7V) of its I-V characteristics. Aslo assume that the voltage across the diode is independent of current above the knee point. If V_(B)=5V , what should be the value of R to estabilish the current of 5mA in the circuit?
