WebPower = 60 watts. Energy = 60 x 12 = 0.72 kW h. In this scenario, the power consumed during the whole day varies as one bulb is turned ON for only 12 hours, so we have to calculate average power, Average Power = Total energy consumed / Total time taken. Therefore, the average power for our light bulbs will be, = (1.44 + 0.72) / 24 = 0.092 kW WebDec 21, 2024 · Power is the product of voltage and curren, so the equation is as follows: P = V x I With this formula you can calculate, for example, the power of a light bulb. If you know that the battery voltage is 18V and current is 6A, you can that the wattage will be 108 with the following calculation: P = 6A x 18V = 108 watts How to calculate power?
