Valve Electroni...

Number of secondary electrons emitted per number of primary electrons depends on

In a diode, when there is a saturation current, the plate resistance will be

The grid voltage of any triode valve is changed from -1 volt to -3 volt and the mutual conductance is 3× 10⁻⁴ mho. The change in plate circuit current will be

For the plate voltage, the plate current in a triode valve is maximum when the potential of :

The amplification factor of a triode is 20. If the grid potential is reduced by 0.2 volt  then keep the plate current constant its plate voltage is to be increased by

The amplification produced by a triode is due to the action of

In a triode amplifier, the value of maximum gain is equal to

The voltage gain of a triode depends upon

In a triode value

In the circuit of a triode value, 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 value is
