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.
DC Circuit Theory: Voltage, Current, Resistance, Power & Ohms Law
WEBApr 4, 2018 · One Volt is by definition, the consumption of energy of one joule per electric charge of one coulomb. The relationship is as described. V = Potential Energy / Charge Or 1V = 1 J/C. Where, J is denoted as Joule and C is coulomb. One Volt voltage drop occurs when a current of 1 amp flow through resistance of 1 ohm.
