Which is the wrong statement in following sentences? A device in which $P$ and $N$-type semiconductors are used is more useful then a vacuum type because
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
The width of forbidden gap in silicon crystal is $1.1\ eV$. When the crystal is converted in to a $N$-type semiconductor the distance of Fermi level from conduction band is
The transfer ratio of a transistor is $50.$ The input resistance of the transistor when used in the common-emitter configuration is $1 k \Omega$. The peak value for an A.C input voltage of $0.01 V$ peak is
For a triode $r_p=10 \ kilo \ ohm$ and $g_m=3 \ milli \ mho$. If the load resistance is double of plate resistance, then the value of voltage gain will be
