ALTERNATIVE METHODS FOR RELATING ELECTRICAL TO MECHANICAL QUANTITIES THROUGH A POWER EQUATION

The problem of linking the mechanical with the electrical units and the solution based on the watt as a key unit related to the Planck constant through the second are considered. Some methods involving dynamic voltage systems are presented in principle, as possible alternatives to the moving-coil current balances, which yield equations between electrical and mechanical power developed both by gravitational and inertial forces.
