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.
30 mA
39 mA
49 mA
20 mA
Answer: Option
Explanation:

IE = aIE + ICBO and approximated.

But a is not given in the question. It is not possible to find.
