AC waveform is a graph that tells the degree and radiant. On the graph the degrees is graphed in top and the radiant is on bottom.

Capacitors resist a change in voltage, inversely proportional to their capacitance. As a result, transients in the AC line tend to be filtered out.
define the maximum value of an ac wave form
the number u are seeking is 0.639
Not really. DC is not a sine wave at all. It is a flat line, in terms of time. On the other hand, if the DC is coming from a power supply that is rectifying AC and filtering it, but not regulating it, then under load conditions, it will exhibit a semi triangular waveform. It will increase when the input AC rises above the diode forward bias point and then it will follow the input AC. It will decrease linearly when the input AC reaches is peak and then starts back down, with a slope proportional to the load. As such, it is a periodic waveform, and by Fourier analysis, it is then a sum of various sine waves. Even if you don't want to get "technical" by looking at Fourier, you can still compare the semi triangular waveform with the input AC waveform, and see that they "fit together". So, yes, 12 volt DC from a power supply is a modified sine wave, unless, of course, there is a regulator stage in the power supply - in that case, it should be flat, as stated first, above.
AC waveform is sinusoidal waveform it has both positives and negative cycles so we dont have a standard constant value to do Measurements so instead of using AC quantities we use ROOT mean square values which is obtained by dividing Vpp(peak to peak voltage) by 1.414AnswerThe rms-value of an AC current is the same as as the value of DC current that will do the same amount of work. For example, 10 A (rms) AC will do exactly the same amount of work as 10 A DC.
