Circuit Analysis

Publisher Summary

This chapter illustrates Circuit Analysis. Electrons are charged particles. Charged objects are attracted to other charged particles or objects. Charged objects come in two forms—negative and positive. Unlike charges attract, and like charges repel. Electrons are negative and positrons are positive, but while electrons are stable in the universe, positrons encounter an electron almost immediately after production, resulting in mutual annihilation and a pair of 511 keV gamma rays. An electron is very small, and does not have much of a charge, so one needs a more practical unit for defining charge. That practical unit is the coulomb (C). One could say that 1 C of charge had flowed between one point and ...
