Next: The Capacitor and Ampère's Up: A Radically Modern Approach Previous: Problems Contents
Various electronic devices are considered in this section. This is useful not only for understanding these devices but also for revealing new aspects of electromagnetism. The capacitor is first discussed and Ampère's law is introduced. The theory of magnetic inductance is then developed. Ohm's law and the resistor are treated. The energy associated with electric and magnetic fields is calculated and Kirchhoff's laws for electric circuits are briefly discussed.
