For a thermionic emitter (metallic) if $J$ represents the current density and $T$ is its absolute temperature then the correct curve between $\log _e \frac{J}{T^2}$ and $\frac{1}{T}$ is
The amplification factor of a triode is $20$ and trans-conductance is $3$ milli mho and load resistance $3 \times 10^4\ \Omega$, then the voltage gain is
The grid voltage of any triode valve is changed from $-1$ volt to $-3$ volt and the mutual conductance is $3 \times 10^{-4} mho$. The change in plate circuit current will be
In the $C B$ mode of a transistor, when the collector voltage is changed by $0.5$ volt. The collector current changes by $0.05\ mA$. The output resistance will be
