Power in general is defined as energy over time. Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s) which means that 1 kW = 1000 J/s.
What is watt formula?
Amps (A) x Volts (V) x Power Factor = Watts (W)
How many joules of energy does a 100 watt?
P = 100 W = 100 J/s.
How do you calculate joules?
Multiply watts by seconds to get joules.
A 1 Watt device consumes 1 Joule of energy every 1 second. If you multiply the number of watts by the number of seconds, you’ll end up with joules. To find out how much energy a 60W light bulb consumes in 120 seconds, simply multiply (60 watts) x (120 seconds) = 7200 Joules.
How do I calculate power?
Power is equal to work divided by time.
In this example, P = 9000 J / 60 s = 150 W . You can also use our power calculator to find work – simply insert the values of power and time.
What is joule in electricity?
In electrical terms, the joule equals one watt-second—i.e., the energy released in one second by a current of one ampere through a resistance of one ohm.
How do you convert Millij to J?
To convert a megajoule measurement to a joule measurement, multiply the energy by the conversion ratio. The energy in joules is equal to the megajoules multiplied by 1,000,000.
How many joules is a GJ?
The prefix “giga” means “billion,” so a gigajoule (GJ) equals one billion joules.
How do you convert KV to V?
To convert a kilovolt measurement to a volt measurement, multiply the voltage by the conversion ratio. The voltage in volts is equal to the kilovolts multiplied by 1,000.
How do you convert joules to watts without time?
The energy in watt-hours is equal to the joules divided by 3,600.
How do you convert kJ s to kW?
kJ/s↔kW 1 kJ/s = 1 kW.
