In a load curve the highest point represents

The correct answer is: A. peak demand.

A load curve is a graph that shows the amount of electricity that is being used at a particular time. The highest point on the load curve represents the peak demand, which is the maximum amount of electricity that is being used at any one time. Peak demand usually occurs during the day, when people are awake and using electricity for activities such as cooking, cleaning, and watching TV.

Average demand is the total amount of electricity that is used over a period of time, divided by the length of that period. Diversified demand is a type of demand that is spread out over a variety of different times and places.

I hope this helps!
