In perfect competition , the marginal cost curve intersects the average cost curve

In perfect competition, the marginal cost (MC) curve represents the additional cost incurred by the firm for producing one more unit of output. The average cost (AC) curve represents the cost per unit of output, obtained by dividing the total cost by the quantity produced. When the MC curve intersects the AC curve, it indicates that the firm is producing at the lowest possible cost. If the MC curve intersects the AC curve from below at its lowest point, it means that the cost of producing an additional unit is less than the average cost of all the units produced. This situation is ideal for the firm since it is producing at the lowest possible cost and maximizing its profits.
