For a CE -transistor amplifier the audio signal voltage across the collector resistance of 2 k`Omega `is 2V. Given the current amplification factor of the transistor is 100 find the input signal voltage and base current if the base resistance is 1 k `Omega`.

Explanation

Given `R_(C)=2 kOmega,V_(CC)=2V ,beta=100, R_(beta)=1 kOmega`
The current amplification factor `beta=I_(C)/I_(beta)`
`I_(C)=V_("CC")/(R_(C))=(2)/(2xx10^(3))=1`mA
`I_(B)=(I_(C))/(beta)=(1)/(100) =0.01 "mA" =10 mu` A
`:. (V_(0))/(V_(i))=(betaR_(C))/(R_(i))" "" or " (2)/(V_(i))=100xx(2000)/(1000)" ""or"V_(i)=0.01` V
