An equal product curve represents all those combinations of two inputs which are capable of producing the same level of output. An iso-product curve can be drawn with the help of iso-quant schedule.
An iso-quant map has different iso-quant curves representing the different combinations of factors of production,yielding the different levels of output. In simple term, an iso-quant map is a family of iso-quants. In other words, if more than One iso-quant is drawn in a diagram, it is called iso-quant map.
