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.
