    A student performs an experiment for drawing the static characteristic curve of a triode value in the laboratory. The following data were obtained from the linear portion of the curves:

    Grid voltage V$$_g$$ (volt)$$-2.0$$   $$-3.5$$  $$-2.0$$
    Plate voltage V$$_p$$ (volt) $$180$$$$180$$$$120$$
    Plate current I$$_p$$ (mA)$$15$$$$7$$$$10$$
