The demand for a commodity that serves two or more purposes is

The demand for a commodity that serves two or more purposes is known as composite demand. This means that the commodity is demanded for different uses or purposes, and the demand for the commodity is influenced by the demand for these different uses. For example, electricity is demanded for various purposes such as lighting, heating, and powering electronic devices, and the demand for electricity for each purpose is different. The total demand for electricity is the composite demand, which is influenced by the demand for each specific use. If the demand for one use of the commodity increases, the demand for the commodity as a whole may also increase. Conversely, if the demand for one use of the commodity decreases, the demand for the commodity as a whole may decrease.
