Chapter 12 Alternating-Current Circuits
web.mit.eduAlternating-Current Circuits 12.1 AC Sources In Chapter 10 we learned that changing magnetic flux can induce an emf according to Faraday’s law of induction. In particular, if a coil rotates in the presence of a magnetic field, the induced emf varies sinusoidally with time and leads to an alternating current (AC), and provides a source of AC ...

www.austincc.eduMFMcGraw-PHY 2426 Chap31-AC Circuits-Revised: 6/24/2012 24 Average Power - Inductors Inductors don’t dissipate energy, they store energy. The voltage and the current are out of phase by 90 o. As we saw with Work, energy changed only when a portion of the force was in the direction of the displacement. In electrical circuits energy is
Chapter 24: Alternating-Current Circuits
www.csun.eduThe image shows an inductor (L = 0.22 mH) in series with a 15-Ω resistor. These elements are in parallel with a second 15-Ω resistor. An ac generator powers the circuit with an rms voltage of 65 V. In the limit of high frequency, the inductor behaves like a very large resistor. In
