The watts equation for an electrical circuit takes into account the voltage across the circuit V, measured in volts, and the current I, measured in amps, passing through it. In mechanics, the definition of power is the rate of doing work W. It's defined as W...
The Watt (W) is a unit for power i.e. the energy used (or supplied) per unit time. 1 J/s (Joule per second) = 1 W (Watt) Power is sometimes expressed in alternate units like BTU/hr or Horsepower (hp) Power-Units Conversion 1kW (KiloWatt) = 3414 BTU/hr 0.746kW= 1hp Powe...
The watt is a power or radiant flux measurement unit. It is defined as a derived unit of (in SI base units) 1 kgm2s3 or, equivalently, 1 joule per second in the International System of Units (SI). It is used to calculate the rate at which energy is transferred.How to convert dBm...
Is the P in Joule's law equal to current?How to convert km/h to ft/s with a formulaThe power P is defined as energy spent per time. P = E/t, where the energy is I Joules, the time in seconds and the power in Watts, where a Watt is a Joule per second. If a heavy load ...
Power Formula 1– Electrical power equation:PowerP=I×V=R×I2=V2⁄R where powerPis in watts, voltageVis in volts and currentIis in amperes (DC). If there is AC, look also at the power factorPF= cosφandφ= power factor angle ...
Verify that the units of a volt-ampere are watts, as implied by the equationP=IV. Electric Power Measurement: Electrical power can be evaluated in an electrical circuit if a voltage across the circuit and current in the circuit is known. It can also be determined i...
1 Joule/second is 1 Watt. If you intended to make it some dimensionless quantity say a coefficient of error, or a percent error you must not label it as Power per unit Area which is W/m². Perhaps you both need some re-study of some fundamental first principles! (although you...
in the ocean. There is no “lag” or “in the pipeline” possible with Equation 1. The atmosphere has far too small a thermal mass to store a significant amount of energy. The earth warms too slowly to serve as a reservoir for annual changes. Global ice amounts are fairly stable (...
Equation 1:T= (j*/σ)0.25 WhereTis the thermodynamic temperature in Kelvin. j*is the black body radiant emittance in Watts per square metre. σis the Stefan-Boltzmann constant of proportionality. (Sigma has a value of 5.670373 * 10-8W m-2K-4) ...
Using the mainstream equation, though, the true equilibrium warming from doubled CO2is even smaller. It is1.13times the reference warming of 1.04 K: i.e., a harmless1.17 K.To make sure, ten separate official estimates of manmade radiative forcing were studied. In each case, global warming ...
