Consider an n-p-n transitor with its base-emitter junction forward biased and collector base junction reverse biased. Which of the following statements are true?

In a p-n junction diode, the current I can be expressed as I=I_(0)"exp"((eV)/(2k_(B)T)-1) where I_(0) is called the reverse saturation current, V is the voltage across the diode and is positive for forward bias and negative for reverse bias, and I is the current through the diode, k_(B) is the Boltzmann constant (8.6xx10^(-5)eV//K) and T is the absolute temperature. If for a given diode I_(0)=5xx10^(-12) A and T = 300 K, then (a) What will be the forward current at a forward voltage of 0.6 V ? (b) What will be the increase in the current if the voltage across the diode is increased to 0.7 V ? (c ) What is the dynamic resistance? (d) What will be the current if reverse bias voltage changes from 1 V to 2 V ?
