Power P I V R I2 V2 R where power P is in watts voltage V is in volts and current I is in amperes DC.
Watts formula physics. Watts specifies the rate at which energy is transferred. 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 voltage V in volts V times the current I in amps A.
What are two units of work. 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. The formula for calculating wattage is.
Electrical and mechanical power calculation strength Power Formula 1 Electrical power equation. How to Calculate Watts W V I For example a current of 2A flowing through a bulb with a voltage of 12V across it generates 24W of power. The conversion from watts to horsepower is.
The power P in watts W is equal to the squared current I in amps A times the resistance R in ohms Ω. It gives the relationships between power watts current amps and voltage volt. The energy consumption formula is articulated as Where E is energy in kilowatt-hourskWh P is power in Watts.
W is a unit of power or radiant flux. Another common but popular unit of power that motors are rated in is watts. Watts is the SI unit of Power P.
The unit for work is the joule J so a Watt is the same as a joulesecond or Js. Volts is the SI unit of potential difference and EMF. What is the formula to calculate watts.
