Watts equation

What is the formula for Watts?

To obtain Watts you need both Amps and Volts: The formula is (A)*(V) = (W). For example, if you have a current of 2 A and a voltage of 5 V, the power is 2A * 5V = 10W. This comes from the equation P = I * V. Where P is the power in Watts, I is the current in Amps and V is the voltage in Volts.

What are Watts equal to?

Watt, unit of power in the International System of Units (SI) equal to one joule of work performed per second, or to 1/746 horsepower. An equivalent is the power dissipated in an electrical conductor carrying one ampere current between points at one volt potential difference.

How do you calculate watts to amps?

Amps calculation with line to line voltageI(A) = P(W) / (√3 × PF × VL-L(V) ) So amps are equal to watts divided by square root of 3 times power factor times volts.amps = watts / (√3 × PF × volts) or.A = W / (√3 × PF × V) Example. I = 330W / (√3 × 0.8 × 110V) = 2.165A. Amps calculation with line to neutral voltage.

How do you calculate power Average Watts?

How to calculate my energy consumptionDevice Wattage (watts) x Hours Used Per Day = Watt-hours (Wh) per Day.Device Usage (Wh) / 1000 (Wh/kWh) = Device Usage in kWh.Daily Usage (kWh) x 30 (Days) = Approximate Monthly Usage (kWh/Month)

Are watts per hour?

Power is the rate at which energy is generated or consumed and hence is measured in units (e.g. watts) that represent energy per unit time. For example, when a light bulb with a power rating of 100W is turned on for one hour, the energy used is 100 watt hours (W. h), 0.1 kilowatt hour, or 360 kJ.

How do I calculate kVA?

Calculation with line to line voltageS(kVA) = √3 × I(A) × VL-L(V) / 1000.So kilovolt-amps are equal to √3 times amps times volts divided by 1000.kilovolt-amps = √3 × amps × volts / 1000.kVA = √3 × A ⋅ V / 1000.S = √3 × 12A × 190V / 1000 = 3.949kVA.
