Electrical energy is equal to what times time
WebSolution. Begin with the equation of the time-averaged power of a sinusoidal wave on a string: P = 1 2 μ A 2 ω 2 v. P = 1 2 μ A 2 ω 2 v. The amplitude is given, so we need to calculate the linear mass density of the string, the angular frequency of the wave on the string, and the speed of the wave on the string. WebThe relation between power and energy is that power has energy units divided by time. The unit of power is watts. ... When force and length is doubled, energy will increase by 4 times. The relationship between energy, force, and distance is given as: Energy = force x distance. Therefore, E = f x d ... One unit of electrical energy is equal to 3 ...
