Consider two pnp bipolar junction transistors. For first transistor when emitter to collector voltage is 5 V, VEB is 0.85 V and emitter current is 10 A. (The β for this transistor is 15). Second BJT conducts with collector current of 1 mA and VEB = 0.70. The ratio of emitter base junction area of first transistor to second transistor is ______.
