Q1:

For an npn transistor connected as shown in the figure VBE = 0.7 volts. Given that reverse saturation current of the junction at room temperature 300K is 10-13A, the emitter current.

A 30 mA

B 39 mA

C 49 mA

D 20 mA

ANS:C - 49 mA

IE = aIE + ICBO and approximated. But a is not given in the question. It is not possible to find.
