17. Both the static and the dynamic characteristic curves depict the
behavior of electron tubes.
The methods of obtaining the curves
differ in that the dynamic curves are obtained
a.
by applying ac voltages to the tubes, and the static curves
are obtained by applying do voltages.
b.
by applying do voltages to the tubes, and the static curves
are obtained by applying ac voltages.
c.
when there is NO load in the circuit, and the static curves
are obtained when there is a load in the circuit.
d.
when there is a load in the circuit, and the static curves
are obtained when there is NO load in the circuit.
