Load curve of a power plant has always

Solution (By Examveda Team)

In the context of a power plant's load curve, it typically exhibits a negative slope. This means that as the load on the power plant increases, the curve tends to slope downwards. This negative slope indicates that the power plant's output decreases as the load demand increases. This phenomenon is quite common in power generation systems, where the power plant adjusts its output to match the varying demand for electricity throughout the day.

Options A and B are incorrect because:
Option A: A load curve with a zero slope would imply that the power plant maintains a constant output regardless of the load demand, which is not typical in real-world scenarios.
Option B: A load curve with a positive slope would suggest that the power plant's output increases as the load demand increases, which is also uncommon in most power generation systems.

Option D is incorrect because it suggests that the load curve can have any combination of zero, positive, or negative slopes. However, in the context of power generation, a negative slope is the most commonly observed characteristic of a load curve, reflecting the typical behavior of power plants to reduce output as demand decreases and vice versa.
