The correct answer is: The operating point may or may not lie on the a.c. load line.
An a.c. load line is a graphical representation of the relationship between the voltage and current of an amplifier under load. The operating point is the point on the load line that represents the actual operating conditions of the amplifier.
The operating point may or may not lie on the a.c. load line, depending on the values of the load resistance and the amplifier’s internal resistance. If the load resistance is equal to the amplifier’s internal resistance, then the operating point will lie on the load line. However, if the load resistance is not equal to the amplifier’s internal resistance, then the operating point will not lie on the load line.
The following are the explanations of each option:
- Option A: The operating point also line. This option is incorrect because the operating point may or may not lie on the a.c. load line.
- Option B: The operating point does not lie. This option is incorrect because the operating point may or may not lie on the a.c. load line.
- Option C: The operating point may or may not lie. This option is correct because the operating point may or may not lie on the a.c. load line.
- Option D: Data insufficient. This option is incorrect because the data is sufficient to determine that the operating point may or may not lie on the a.c. load line.
