Q.8. p – n – p transistor circuit, the collector is 10 ma , If 90 % of the reach the Collector, find emitter and base currents.

Ans:              Here, I E = 10 m A

As 90 % of the holes reach the collector, so the collector current ,

                      I c = 90 % of I E = 90/100 IE

                      I E = 100/900 Ic = 100/90 x 10 = 11 m A.

                      Base Current, I B = I E – I c = 11-10 = 1 mA.

Q.9. A photodiode is fabricated froma semi conductor with band gap of 2.8 e V . Can it detect a wave of 6000 nm? Justify.

Ans : Energy Corresponding to Wave length 6000 nm is
