A company that earns a return on equity in excess of its cost of equity capital has added value. (For more on ROE, read Keep Your Eyes On The ROE .). Calculating the Cost of Equity The cost of equity can be a bit tricky to calculate as share capital carries no explicit cost. Unlike debt, which the company must pay in the form of predetermined interest, equity does not have a concrete price that the company must pay, but that doesn't mean no cost of equity exists.
Boltzmann's constant, also called the Boltzmann constant and symbolized k or k B, defines the relation between absolute temperature and the kinetic energy contained in each molecule of an ideal gas.he value of Boltzmann's constant is approximately 1.3807 x 10 -23 joule s per kelvin (J Â· K -1).
average kinetic energy of molecules=3kT/2, where k is the Boltzmann constant. Temperature is a measure of the energy of thermal motion and, at a temperature of zero, the energy reaches a minimum (quantum mechanically, the zero-point motion remains at 0 K). In July, 1995, physicists in Boulder, Colo.
