Physics power unit
WebbUnit of Power. Power, in general, is defined as the rate at which energy is transferred or converted or the rate of doing work. Thus, power can be calculated using the formula P = W / t. On the other hand, power is a scalar quantity and is basically the amount of energy consumed per unit of time which has no direction. Webb3 sep. 2024 · Power Dimensional Formula. Dimensional formula is [ML²T -3 ]. Its other units are kilowatt and horse power, 1 kilowatt = 1000 watt. 1 horse power =746 watt. 1 kWh = 3.6 x 10 6 J. Work, Energy and Power: Work, energy and power are the three quantities which are inter-related to each other. The rate of doing work is called power.
