remains closed and the source continues to supply the sinusoidal voltage. In this chapter, we develop a technique for calculating the steady-state response directly, thus avoiding the problem of solving[r]

We conclude our first look at mutual inductance with a discussion of the total energy stored in magnetically coupled coils. In doing so, we will confirm two observation[r]

obtained makes sense. Does the magnitude of the answer seem rea- sonable? Is the solution physically realizable? You may want to go further and rework the problem via an alternative method. Doing so will not only test[r]

2.4 Kirchhoff's Laws
A circuit is said to be solved when the voltage across and the current in every element have been determined. Ohm's law is an important equation for deriving such solutions. However, Ohm's law may not be enough to provide a complete solution. As we shall see in tryi[r]

in the air across the switch, a phenomenon called arcing. The arc across
the switch prevents the current from dropping to zero instantaneously. Switching inductive circuits is an important engineering problem, because arcing and voltage surges must be controlled to prevent equipmen[r]

A Review of Self-Inductance
The concept of inductance can be traced to Michael Faraday, who did pio- neering work in this area in the early 1800s. Faraday postulated that a magnetic field consists of lines of force surrounding the current-carrying conductor. Visualiz[r]

Many of the circuits that are used today to control flashing lights are based on electronic circuits that are beyond the scope of this text. Nevertheless we can get a feel for the thought process involved in designing a flashing light circuit by analyzing a circuit co[r]

induced voltage to the current. We discuss this quantitative rela- tionship in Section 6.1.
A capacitor is an electrical component that consists of two conductors separated by an insulator or dielectric material. The[r]

steady-state value.
