A unit of a company's capital is a share.
A share represents a unit of ownership in a company. When a company wants to raise capital to fund its operations or expansion, it can sell shares of its stock to investors. Each share entitles the owner to a portion of the company's profits, as well as the right to vote on important company decisions.
The value of a share can fluctuate based on a variety of factors, including the company's financial performance, market conditions, and investor sentiment. Investors can buy and sell shares on stock exchanges, where the price of a share is determined by the forces of supply and demand.
In summary, a share represents a unit of ownership in a company and is one way that companies can raise capital to fund their operations.
