In a common-emitter transistor amplifier, signal voltage across the collector resistance of 2 kΩ is 2 volt. What should be the value of resistance RB in series with VBB voltage supply of 2 volt in the input circuit, if the DC base current is 10 times the signal current in RB ?(Given : Base emitter voltage, VBE = 0.6 voit; and current amplification factor β = 100 .
