Web6 apr. 2024 · The formula for consumption of energy is given below-. E = P* (t/100) In this formula, E refers to the measured Joules or kilowatt per hour (kWh). P refers to power used per unit in watts. t refers to the time over which the power is consumed. Hence, to calculate the consumption of energy one can use this formula. Web6 apr. 2024 · Power is measured in watts. Power is also sometimes measured in horsepower, where one horsepower is equal to 750 watts. Work output can be calculated using the formula Work done/time. For instance, if an electric motor raises a 1000kg beam, 4 meters in 10 seconds, where g is equal to 9.8,m/s, then the power is calculated as:
