Cálculo de Potência Elétrica

App developed to perform calculations that electric power is obtained by multiplying the voltage (V) for the current (A), the result of which is in watts (W) and current calculations (A) and voltage (V). Calculations: Power (W) = Current (A) x Voltage (V) Current (A) = Power (W) ÷ voltage (V) and voltage (V) = Power (W) ÷ Current (A). The watt (symbol: W) is the SI unit of power. It is equivalent to one joule per second (1 J / s) .The unit watt is named after James Watt for his contributions to the development of the steam engine, and was adopted by the Second Congress of the British Association for the Advancement of Science in 1889.
