Plate resistance of two triode valves is $2 k \Omega$ and $4 k \Omega$, amplification factor of each of the valves is $40.$ The ratio of voltage amplification, when used with $4 k \Omega$ load resistance, will be
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
With a change of load resistance of a triode, used as an amplifier, from $50$ kilo ohms to $100$ kilo ohms, its voltage amplification changes from $25$ to $30.$ Plate resistance of the triode is
