Supply is one of the most complex parts of economics, filled with mathematical formulas, graphs, and equations. The collection can be any goods, services, or labour factors.

Supply is the graph plotted between quantity and price. The supply curve graph consists of different types of amounts and all prices available at that time in the market.

The supply curve is drawn by taking all the possible prices and may be available quantities in mind.

There is a fundamental concept of economics called The Law of Supply. It claims that if the price of a particular item increases, the production rate of that item also increases.

That is, its quantity increases. Similarly, if the price of that item decreases, the production of that item also decreases. That is, its quantity deteriorates. 

For example, if the demand for a particular soap in the market increases, the firm will try to maximize the sale of that item to gain profit.

So, as a result, they will increase the production level of that particular soap in the firm rather than those less in demand.

With the increase in the supply concerning the regular supply, the curve shifts rightwards. This happens when the quantity supplied increases with the market prices as well.

On the other hand, the supply curve shifts towards the left when the market prices and quantity decrease.

For example, a ticket house wants to sell 1000 tickets for Rs.20/-. And the same place is also ready to sell 750 tickets for Rs.10/-. So here, the provider wants to provide a particular amount of tickets at a specific amount of rupees.

This process is called quantity supplied when a specific amount is provided at the amount the provider sets per their needs.

The quantity supply also differs from the total supply. Quantity supply is susceptible to market price rates. The quantity supplied is nearly the entire supply when the price is higher.

But when the prices are lower, the quantity supplied has a high range difference from the total supply.

It depends on the current economic situation. It can also be affected due to the competition of similar products in the market. A minimal difference in these factors affects the supply curve a lot.
