Supply and demand curve:The law of supply and demand is a theory that explains the interaction between the sellers of a resource and the buyers for that resource.It is visualized on a chart at the intersection of the supply and demand curve. This intersection is the market price at which suppliers bring to market that same quantity of product that consumers will be willing to buy. They then say that Supply and Demand are in equilibrium. | Rohit Chandra Thakur | Facebook
