Power transmission

特許 係属中 Power transmission is the movement of energy from its place of generation to a location where it is applied to performing useful work. Power is defined formally as units of energy per unit time. In SI units: \text{watt} = \frac{\text{joule}}{\text{second}} = \frac{\text{newton}\times\text{meter}}{\text{second}} Since the development of technology, transmission and storage systems have been of immense interest to technologists and technology users.
