Chapter 5 – Force and Motion I

Chapter 5 – Force and Motion I I. Newton’s first law: If no net force acts on a body, then the body’s velocity cannot change; the body cannot accelerate v = constant in magnitude and direction. - Principle of superposition: when two or more forces act on a body, the net force can be obtained by adding the individual forces vectorially.

Chapter 31 Alternating Current Circuits

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 dissipated only if a portion of the voltage is in phase with the ...

Capacitor and inductors - MIT OpenCourseWare

to circuits that contain capacitors and inductors. Unlike the resistor which dissipates energy, ideal capacitors and inductors store energy rather than dissipating it. Capacitor: In both digital and analog electronic circuits a capacitor is a fundamental element. It enables the filtering of signals and it provides a fundamental memory element.

Chapter 3: Capacitors, Inductors, and Complex Impedance

Chapter 3: Capacitors, Inductors, and Complex Impedance In this chapter we introduce the concept of complex resistance, or impedance, by studying two reactive circuit elements, the capacitor and the inductor. We will study capacitors and inductors using differential equations and Fourier analysis and from these derive their impedance.
