How are amplitude and power related?
The time-averaged power of a sinusoidal wave is proportional to the square of the amplitude of the wave and the square of the angular frequency of the wave. This is true for most mechanical waves. If either the angular frequency or the amplitude of the wave were doubled, the power would increase by a factor of four.
Does amplitude mean power?
The first characteristic of AC power is its "amplitude". Amplitude is the maximum value of current or voltage. It is represented by either of the two peaks of the since wave. This voltage level is also referred to as the peak voltage, and can be either positive or negative.
Is amplitude directly proportional to energy?
In fact, a wave's energy is directly proportional to its amplitude squared because W ∝ Fx = kx2. The energy effects of a wave depend on time as well as amplitude.
Why does energy increase as amplitude increases?
The length of the amplitude is increased by increasing the length of the wave, which leads to higher amplitude and high energy of particles.
