The slope of plate characteristic of a vacuum tube diode for certain operating point 10⁻³ mA/V​. The plate resistance of the diode and its nature respectively

A triode has a mutual conductance of 2×10⁻³ mho and an amplification factor of 50. The anode is connected through a resistance of 25×10³ phm to a 250 volts supply. The voltages gain of this amplifier is

14×10¹⁵ electrons each the anode per second. If the power consumed is 448milliwatts, then the plate (anode) voltage is

If the amplification factor of a triode (μ) is 22 and its plate resistance is 6600 ohm , then the mutual conductance of this value in mho is

For a triode at V_g​ = −1 volt, the following observation were taken V_p​ = 75V, I_p​=2mA, V_p​=100 V, I_p​=4ma. The value of plate resistance will be

The triode constant is out of the following

The unit of mutual conductance of a triode value is

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
