Induction and Inductance

A New Look at Electric Potential

A New Look at Electric Potential Induced electric fields are produced not by static charges but by a changing magnetic flux. Although electric fields produced in either way exert forces on charged particles. there is an important difference between them. The simplest evidence of this difference is that the field lines of induced electric fields form closed loops. …

RL Circuits

RL Circuits In Section 28-8 we saw that if we suddenly introduce an emf’l!; into a single-loop circuit containing a resistor R and a capacitor C, the charge on the capacitor does  not build up immediately to its final equilibrium value C’l!; but approaches it in an exponential fashion: The rate at which the charge builds …
