WebApr 10, 2024 · SI Unit of power is Watt; 1 Watt = 1 J/s = 1 kg -m 2 /s 3. 1 watt is equal to 1 joule of work done in 1 second. Watt is named after the famous inventor James Watt. Watt is a scalar quantity, which means it doesn’t contain direction. The formula for power is Power = Work / time; P = W / t. WebIf we consider the equation for power, P = \Delta E / \Delta t P = ΔE /Δt , then this is the measurement we get when \Delta t Δt is extremely small. If you are lucky enough to have a plot of power vs time, the instantaneous power is simply the value you would read from … Thermal energy refers to the energy contained within a system that is … cteph type https://new-lavie.com
