It is the highest value of the amplitude, called the peak value. Scroll down to related links and look at "RMS voltage, peak voltage and peak-to-peak voltage". Look at the figure in the middle below the headline "RMS voltage, peak voltage and peak-to-peak voltage".

At any instant of time you can measure the current amplitude of an alternating waveform. As the waveform cycles at the operating frequency at some point it reaches its maximum amplitude for the cycle. That is the peak value.

What is peak to peak?

Peak to Peak is the most positive peak to the negative peak value. Or find any peak value and multiply by 2.


Why is the peak amplitude of voltage load lower than the amplitude of voltage transformer?

Unless otherwise stated, the value of an a.c. current or voltage is expressed in r.m.s. (root mean square) values which, for a sinusoidal waveform, is 0.707 times their peak value. The output of a voltage (or potential) transformer is no different, its measured voltage will be its r.m.s value which is lower than its peak value.


What is rms if sine wave is 20 cm peak to peak?

For a sine wave, the RMS is the amplitude divided by square root of 2. The amplitude is 10 cm. in this case; so the exact value is 10 / root(2), or about 7.For a sine wave, the RMS is the amplitude divided by square root of 2.

What is the Relationship between the peak-to-peak DC voltage across RL and the peak input voltage in full wave rectifier?

The input voltage, an AC Sine Wave will have a Peak-to-Peak value equal to 2X its Peak value. Once rectified, all the Peaks will be either above or below the Zero reference line. They'll look like a series of identical bumps. The net value of the unrectified voltage will be Zero. The positive and negative waveforms canceling each other out. The rectified waveform will be all positive or negative and its net value will be non-zero. Its AVERAGE value will be .636 times its Peak value. Its Root Mean Square (RMS) value will be .707 times its Peak value. Its Peak-to-Peak value will equal 1X the Peak value.

What is the difference between wavelenghtand amplitude?

The wavelength is the distance the wave travels before repeating in meters. The amplitude of the wave is the deflection from peak to trough in units of the wave value, e.g electric field or velocity.

What is the verticle distance between a wave's crest and trough?

The vertical distance between the peak and trough is 2*Amplitude.


How do you measure and wavelength?

The wavelength is the distance from one peak (or trough) of the wave to the next peak (or trough). The amplitude is the distance from the mean value to the top of the peak (or the bottom of the trough). Alternatively, the amplitude is one half of the distance between the height of peak to the depth of the trough.How you measure these depends on the nature of the waves.


What characteristics of sound is determined by amplitude?

The strength or volume of sound. By increasing the amplitude you enlargens the energy because the difference between peak negative and peak positive voltage in the waveform gets bigger. One use positive and negative voltage so that a loudspeaker can Push and Pull the membrane. Amplitude is the difference between Negative and Positive. IE Wave Bottom and Wave Top.


What is the relationship between amplitude and magnitude?

* The term peak amplitude, often shortened to amplitude, is the nonnegative value of the waveform's peak (either positive or negative). * The instantaneous amplitude of is the value of (either positive or negative) at time . * The instantaneous magnitude, or simply magnitude, of is nonnegative and is given by . ALSO Amplitude is the maximum displacement from equilibrium in a sinusoidal wave.Magnitude is just the value of something; typically refering to scalar quantities.


Half the vertical distance between the crest and through of a wave is called the?

The vertical distance between a wave's midpoint and its crest or trough is called is peak amplitude. This differentiates this measurement from the vertical distance from a crest to a trough, which is called its peak-to-peak amplitude.
