How To Calculate Power Consumption Per Hour. The energy E in kilowatt-hours kWh per day is equal to the power P in watts W times number of usage hours per day t divided by 1000 watts per kilowatt. Power Amps x Volts 110 watts amps x 12 Therefore amps every second every hour same thing.
If you multiply this figure in kW by the number of hours it is on you get the kWh. Calculated at 5 rupees per unit. So now we use the above formula to calculate the current amps that the inverter will take from the battery.
The number of hours you use it per day x the number of days uses x wattage of the electrical appliance in watt 1000 kWh energy consumed by appliance If you want to calculate the monthly power consumption by.
Multiply your monthly power consumption with your citys electricity cost per unit. So the product of two numbers 6498 and 08 equals 519. Let us understand the difference between the power consumption of 2-ton 5-star split AC and 2 ton 5-star window AC by calculating the monthly power consumption. For example a device rated at 1500 W thats on for 25 hours.
