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
In the circuit of a triode valve, there is no change in the plate current, when the plate potential is increased from $200$ volt to $220$ volt and the grid potential is decreased from $-0.5$ volt to $-1.3$ volt. The amplification factor of this valve is
