In a common emitter amplifier of a transistor,if the ratio of the voltage gain and current amplification factor is $4$,then the ratio of the collector and base resistances is

In the circuit shown,the value of $\beta$ of the transistor is $48$. If the base current supplied is $200 \mu A$,what is the voltage at the terminal $Y$ (in $V$)?

$A$ common emitter amplifier has a voltage gain of $50$, an input resistance of $100 \ \Omega$, and an output resistance of $200 \ \Omega$. What is the power gain of the amplifier?

In a common base transistor circuit,the current gain is $0.98$. On changing emitter current by $5.00 \,mA$,the change in collector current is ......... $mA$.

$A$ transistor is operated in common emitter configuration at $V_C = 2 \, V$ such that a change in the base current from $100 \, \mu A$ to $300 \, \mu A$ produces a change in the collector current from $10 \, mA$ to $20 \, mA$. The current gain is

In a common emitter $(CE)$ amplifier having a voltage gain $G,$ the transistor used has transconductance $0.03\, mho$ and current gain $25.$ If the above transistor is replaced with another one with transconductance $0.02\, mho$ and current gain $20,$ the voltage gain will be
