$A$ transistor oscillator is a device that is used to:

For a transistor to act as a switch,it must be operated in

The value of $I_c$ for the configuration shown is in $mA$.

For a common emitter transistor amplifier, the current gain is $\beta = 100$. Given the input voltage $V_{in} = 1 \text{ mV}$, input resistance $R_{in} = 1 \text{ k}\Omega$, and load resistance $R_L = 10 \text{ k}\Omega$, calculate the output voltage $V_{out}$ in $\text{V}$.

In a $CE$ transistor amplifier,the audio signal voltage across the collector resistance of $2 \, k\Omega$ is $2 \, V$. If the base resistance is $1 \, k\Omega$ and the current amplification of the transistor is $100$,the input signal voltage is

For a given transistor,if $\alpha = 0.95$,find the common emitter current gain $\beta$.
