Webb. Convert the power to kilowatts. c. Calculate the number of kilowatt-hours of electricity used by the alarm clock if it is left on for one year. d. Calculate the cost of using the alarm clock for one year if your town charges $0.15/kWh. 6. Using the formula for power, calculate the amount of current through a 75-watt light bulb that is connected WebEnergy consumption calculation. 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: E (kWh/day) = P (W) × t (h/day) / 1000 (W/kW)

The voltage between two lines is the line voltage. Three phase power is typically used for induction motors (as it helps reduce the need for a starter capacitor) and heavy loads because it is usually more economical that two-wire/single phase. WebWatts calculation The power P in watts (W) is equal to the voltage V in volts (V) times the current I in amps (A): The power P in watts (W) is equal to the squared voltage V in volts (V) divided by the resistance R in ohms (Ω): The power P in watts (W) is equal to the squared current I in amps (A) times the resistance R in ohms (Ω): the company insurance
