what is perfectly elastic demand

Perfectly elastic demand is a situation in economics where the demand for a product is entirely dependent on the price of the product. This means that even a minimal increase in price will cause the demand to disappear, and a minimal decrease in price will lead to an infinite increase in demand. It is considered a theoretical extreme case and is rarely found in real life. Graphically, a perfectly elastic demand curve is a horizontal line, indicating that the quantity demanded can change infinitely with a small change in price
