What Is the Formula for Energy? Sciencing

WebIn calculating the power in the circuit of Figure 19.21, we used the resistance and Ohm’s law to find the current. Ohm’s law gives the current: I = V / R, which we can insert into the equation for electric power to obtain. P = I V = ( V R) V = V 2 R. This gives the power in terms of only the voltage and the resistance. WebIntensity (physics) In physics, the intensity or flux of radiant energy is the power transferred per unit area, where the area is measured on the plane perpendicular to the direction of propagation of the energy. In the SI system, it has units watts per square metre (W/m 2 ), or kg ⋅ s −3 in base units. Intensity is used most frequently ...
