What is the difference between AC and DC average rms and peak values?
RMS minus ripple current , that is alternating current (sinusoidal wave form )it is including ripple voltage and ripple current . peak current is maximum peak in sinusoidal wave form . general used in choke (filter ) design calculation .AnswerHow do you compare the 'speed' of a circular saw with that of a reciprocating saw? One spins, while the other goes up and down. The answer is that you compare them, not in terms of their individual speeds, but in terms of their 'cutting speeds' (i.e. how fast they cut board).We do the same thing with a.c. and d.c. We compare one with the other in terms of the 'work' they do. So, for example, a 10-A (r.m.s.) a.c current will do precisely the same amount of work as a 10-A d.c. current.So the r.m.s. value of an a.c. current is exactly equivalent to the value of a d.c. current that will achieve the same amount of work. Because voltage is proportional to current, the r.m.s. value of an a.c. voltage and a d.c. voltage are also equivalent to each other.For a sinusoidal a.c. current or voltage, the r.m.s. value is 0.707 times the peak value.
