Question: If the DC collector current, Ic , for an NPN BJT in the forward - active region is equal to 0 . 3 mA then

If the DC collector current, Ic, for an NPN BJT in the forward-active region is equal to 0.3 mA then what is the voltage across the base-emitter junction, Vbe, in millivolts? Assume that the saturation current for this BJT, Is, is equal to 11 fA.(Note that 1 fA =1 femtoamp =1 x 10^-15 A.) Neglect the effects of base-width modulation. Also assume that the thermal voltage is equal to Vt = kt/q =26mV. Since Ic is very sensitive to small changes in Vbe, be sure to give your answer to the nearest millivolt!
