Three amplifiers,each having a voltage gain of $10$,are connected in series. The resultant gain would be

In a common base amplifier,the phase difference between the input signal voltage and the output voltage is

Assertion: In a transistor,the base is made thin.
Reason: $A$ thin base makes the transistor stable.

In a common emitter transistor amplifier, an input signal of $10 \ mV$ is applied. Due to this signal, the change in base current is $50 \ \mu A$ and the corresponding change in collector current is $5 \ mA$. If the load resistance in the collector-emitter circuit is $5 \ k\Omega$, the change in output voltage will be ..... $V$.

In an experiment,the input characteristics are shown for a $CE$ configuration $n-p-n$ transistor for different output voltages. Based on the graph,which of the following is correct?

$A$ transistor is operating in the active mode. $v_1$ is the potential barrier across the base-emitter junction and $v_2$ is the potential barrier across the collector-base junction. $b_1$ is the width of the depletion layer of the base-emitter junction and $b_2$ is the width of the collector-base junction.
