Question
Since Vcc = 12 V, Vin = 721 mV, RB = 780 kohm, RC1 = 14.8 ohm, RC2 = 27.5 ohm, RE = 470 ohm, RL = 47 Q2 and B1 = B2= 100 in the circuit in the figure Find the current (1) flowing through RL? NOTE-1: VBE1 = VBE2 = 0.7 V will be taken. NOTE-2: The output impedances (ro) of the transistors will be neglected.
