GATE ECE 2005 | Question-46

For an $npn$ transistor connected as shown in the figure, $V_{B E}=0.7$ volts. Given that reverse saturation current of the junction at room temperature $300^{\circ} \mathrm{K}$ is $10^{-13} \mathrm{~A}$, the emitter current is

  1. $30 \mathrm{~mA}$.
  2. $39 \mathrm{~mA}$.
  3. $49 \mathrm{~mA}$.
  4. $20 \mathrm{~mA}$.
