Draw and discuss Pentode Plate Characteristics.

Ans:  Pentode Plate Characteristics:  Pentode plate characteristics  (plate  current-plate voltage curves at constant grid voltage) are portrayed in fig. (a).

1.  Characteristics are non-linear below the knee of the curve.

2.  Dip  noticed  in  the  plate  characteristics  of  a  tetrode  is  eliminated  in  the pentode  plate  characteristics.   This  is  because of the  suppression  effect  of  suppressor grid.

3.  Over the major portion (above the knee) of the characteristics plate current is largely independent of plate voltage. So pentode may be thought as a constant current device. A pentode is generally operated in this region.
