The grid voltage of any triode valve is changed from–1 volt to – 3 volt and the mutual conductance is3 × 10^–4 mho. The change in plate circuit current will be

The current in a diode is related to the voltage V by the equation

In an amplifier the load resistance R_L is equal to the plate resistance (r_p). The voltage amplification is equal to

For a given plate-voltage, the plate current in a triode is maximum when the potential of

If R_p = 7 KΩ, g_m = 2.5 millimho, then on increasing plate voltage by 50 V, how much the grid voltage ischanged so that plate current remains the same

The current in a triode at anode potential 100 V and grid potential – 1.2 V is 7.5 mA. If grid potential is changed to – 2.2 V, the current becomes 5.5 mA. The value of transconductance (g_m) will be

In a triode amplifier, μ = 25, r_p= 40 kilo ohm and load resistance R_L = 10 kilo ohm. If the input signal voltage is 0.5 volt, then output signal voltage will be

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

In an experiment, the saturation in the plate current in a diode is observed at 240 V. But a student still wants to increase the plate current. It can be done, if

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