The instantaneous value of current in an AC circuit is represented by 150 sin 2π x 30t What are the amplitude and frequency of the AC wave?

The amplitude is 150; 30


Root-mean-square voltage in ac?

rms voltage will give the ability to predict how much work will be done by an ac voltage. the rms value of a pure sine wave is 0.707 times it's maximum amplitude.


Does amplitude mean louder?

No. Amplitude refers to the height of a wave. If the wave is a sound wave a larger amplitude would mean a louder sound.


What does it mean when a wave has a large amplitude?

Bigger the amplitude, bigger the wave.


What is the difference in the direction of the magnetic field produced around conductor by dc flow and ac flow?

The direction and amplitude of the magnetic field around a wire depend on the direction and amplitude of the current through the wire. When the wire carries DC, the direction and amplitude of the current in the wire are constant, so the direction and amplitude of the magnetic field around the wire are constant. When the wire carries AC, the direction of the current in the wire is periodically reversing and its amplitude typically changes, so the direction of the magnetic field around the wire is periodically reversing and its amplitude is typically changing.


What does a high amplitude mean in nerve conduction studies?

Amplitude is not that important. If anything the area under the curve would be more informative. A good amplitude does mean a good recording though.


What is the relation between amplitude and freq if a transmitter having frequency 500mhz what is the amplitude range if have any formula please tell me about that?

Actually the amplitude depends on your modulator by which you generated your signal you can pick any amplitude you want but here is the formula for frequency modulated signal: Ac here decide the amplitude of the signal and you can see that it is not related to the frequency component of your signal.

What does a sound wave with high amplitude have?

What does the amplitude of a sound wave indicate?

Amplitude is the maximum extent of vibration of a body from its mean position. The amplitude of a sound wave indicates the loudness of the sound.
