For a common emitter amplifier,the current gain is $50$. If the emitter current is $6.6 \ mA$,then the value of the base current is ........ (in $mA$)

In the given transistor circuit,the base current is $35 \mu A$. The value of $R_b$ is.....$k\Omega$.

The voltage gain and the current amplification factor of a transistor in common emitter configuration are $300$ and $60$ respectively. If the collector resistance is $5 \, k\Omega$, then the base resistance is:

In a common emitter transistor amplifier, the output resistance is $500 \text{ k}\Omega$ and the current gain $\beta = 50$. If the power gain of the amplifier is $5 \times 10^6$, what is the input resistance (in $\Omega$)?

In a transistor output characteristic commonly used in common emitter configuration, the base current $I_{B}$, the collector current $I_{C}$, and the collector-emitter voltage $V_{CE}$ have values of the following orders of magnitude in the active region:

$A$ transistor has a voltage gain '$A$'. If a fraction '$\beta$' of its output is fed back to the input of the transistor,then the transistor becomes an oscillator when:
