Ac current formulas are:Ohm's law for reactive circuits:Ohm's law for circuits containing resistance and reactance:Current across the primary (I p ) of a transformer:Current across the secondary (I s ):NOTEHuman reaction to electrical shock is determined by the amount of currentflowing through the body. A 100-milliampere shock for 1 second is usually fatal!More information about current can be found in NEETS, Module 1, Introduction to Matter, Energy,and Direct Current.1-22
InductanceInductance is the characteristic of an electrical conductor that opposes a change in electrical current.The symbol for inductance is L and the basic unit of measurement is the HENRY(H).An inductor has an inductance of 1 henry if an electromotive force (emf) of 1 volt is induced in theinductor when the current through the inductor is changing at the rate of one ampere per second.Mathematically:Mutual inductance:Series inductors without magnetic coupling:Series inductors with magnetic coupling:1-23
