It should be noted that test conditions (temperature, frequency, amplitude, and DC bias value of test voltage among others) frequently have a strong influence on observed device parameters. Safety ratings Capacitors designed for use in applications where failure may pose a risk to the safety of ...
3. A frequency is the number of oscillations in alternating electrical current each second.4. The term frequency may also refer to cycles per second of an electromagnetic wave, such as a sound wave or a light wave. The frequency of light determines its color, as seen by the human eye. ...
Where ρ is resistivity, ω is angular frequency, μ r relative amplitude of complex permeability. In deep within the skin, due to the alternating magnetic field, will produce induction electric field and the induced current, known as the vortex. 翻译结果4复制译文编辑译文朗读译文返回顶部 Where:...
aAmplitude fluctuates widely under the influence of terminal movement. While large fluctuations in average received power are encountered in the case of a bandwidth in which the spread of the frequency spectrum is narrow, such fluctuations become smaller as the bandwidth becomes wider. 宽阔广泛地受终...
A wave is represented by the equation A、Frequency= B、Amplitude=0.001mm C、MaximumVelocity of the Particle 60 mm/sec D、wavevelocity is 100m/s 点击查看答案
Thus, although the frequency of a forced vibration is independent of the natural frequency of the elastic system,the resulting amplitude is affected by both frequencies. Vibrations are also classified as damped or undamped . When friction,air resistance,viscous damping,and all other resisting forces ...
