The truth table for the following circuit is

A transistor can be used

The above configuration is equivalent to the 

For what value of voltage will the reverse current $I_0$ in a $p-n$ junction $Ge$ diode reach $90\%$ of its saturation value at room temperature?

For the following logic circuit, 

$Y=0$ for $A=1, B=1, C=1$
$Y=0$ for $A=0, B=0, C=0$
$Y=1$ for $A=1, B=0, C=0$

The logic gate in the question-marked box will be,

In a full-wave rectifier, circuit operating from $60 \mathrm{Hz}$ main frequency, the fundamental frequency in ripple would be,

For a transistor in common emitter configuration, the current amplification factor is $0.8$. The change in base current when the collector current changes by $24 \mathrm{mA}$ is,
