In the figure, input is applied across $A$ and $C$ and output is taken across $B$ and $D$, then the output is:

In the following common emitter configuration an '$npn$' transistor with current gain $\beta =100$ is used the output voltage of amplifier will be:

In the given transistor circuit, the base current is $35 \mathrm{\mu A}$. The value of $R_b$ if $V_{BE}$ is assumed to negligible:

In the circuit shown here the transistor used has current gain $\beta =100$. What should be the base resistor $R_b$ so that $V_{CE}=5V, V_{BE}=0$:

The output of the given logic gate is $1$  when inputs $A,B$ and $C$ are such that:

The arrangement shown in figure performs the logic function of $a/an$ ....... gate:
