AC Circuit Theory: Introduction, AC Generation, AC vs DC
WEBJan 24, 2018 · In DC, Electrons flow steadily in a single direction or forward, while in AC, electrons alternate their direction of flow in periodic intervals. This also leads to alternation in the voltage level as it switches along from positive to negative in line with the current. Below is a comparison chart to highlight some of the difference between AC ...
DC Motor Speed Control using Arduino and Potentiometer
WEBJun 3, 2015 · Speed Control of DC Motor using Arduino.

AC Circuit Theory (Part 3): Peak, Average and RMS Values
WEBFeb 14, 2018 · Mathematically, it is given by the equation; Where Vpeak is the maximum amplitude of the waveform. For a pure sine wave, similar to the form factor, the crest factor is always fixed at 1.414. We can also Derive Irms from above equation like: 1.414 = Vpeak / (0.707 x Vpeak) Vrms = V peak / 1.414. Vrms = 0.707 x Vpeak.
