Q 41 to 50

The plate current, plate voltage and grid voltage of a 6F6 triode tube are related as i_p = 41 (V_p + 7 V_g)^(1.41) where V_p and V_g are in volts and i_p in microamperes. The tube is operated at V_p = 250 V, V_g = -20 V . Calculate (a) the tube current, (b) the plate resistance, (c) the mutual conductance and (d) the amplification factor.
