Supreme Formula For Power In Watts
For example if you have a power of 10W with a current of 2A the voltage is 10W 2A 5V.
Formula for power in watts. As is implied by the equation for power a unit of power is equivalent to a unit of work divided by a unit of time. AC single phase amps to watts calculation formula. What is power consumption in watts when the current is 3A and the voltage supply is 110V.
The power P in watts W is equal to the voltage V in volts V times the current I in amps A. The watt is named after James Watt 1736-1819 an 18th-century Scottish inventor. The higher the wattage which we now know is the combination of electrical potential and flow the more power and output well see.
W V x I or W I 2 x R or W V 2 R. The power formula for a circuit is P VI where V is in volts and I in amperes. The formula generally given for Power is.
This comes from the equation V P I. For historical reasons the horsepower is occasionally used to describe the power delivered by a machine. The real power P in watts W is equal to the power factor PF times the phase current I in amps A.
For example if you have a 085 power factor 15 kW of power and a voltage of 230 V simply quote your power as 1500 W and calculate. Physicists use power in mechanics and electricity. The power P is equal to current of 3 amps times the voltage of 110 volts.
In the case of the garden hose this would be the amount of water flowing. Watts Law says the relationship between power voltage and current. The Power Formula is used to compute the Power Resistance Voltage or current in an electrical circuit.
