    The plate current in a triode value is maximum when the potential of the grid is
    (a) positive
    (b) zero
    (c) negative
    (d) non-positive
    digAnsr:   a
    Ans : (a) positive
    If the grid voltage is made positive, it will help the electrons move towards the anode, which will help in increasing the current. Thus, the plate current in the triode value is maximum when the potential of the grid is positive.
