a common emitter gives an output of 3v for an input of 0.01v. if current gain of the transistor is 100 and the input resistance is 1 kΩ,  then the collector resistance is?
1)30 kΩ
​2)3 kΩ
 

current gain=output currentinput current=Ic Ib100=Ic Ib this means  Ic = 100 Ib------1voltage gain=3.01=Ic RcIbRb=100 IbRcIb×1000or         Rc = 3000 ohm=3kohmTherefore correct answer is option 2.
