1. INTRODUCTION Generally when most people think about electronics‚ they may initially think of products such as cell phones‚ radios‚ laptop computers‚ etc. others‚ having some engineering background‚ may think of resistors‚ capacitors‚ etc. which are the basic components necessary for electronics to function. Such basic components are fairly limited in number and each having their own characteristic function. Memristor theory was formulated and named by Leon Chua in a 1971 paper. Chua

The electromagnetic field produced around the coils is directly proportional to the magnitude of applied current‚ rate of change in current or frequency and the coil parameters. 5. Coil parameters include: Inductance‚ diameter‚ length‚ and thickness‚ number of turns of wire and core material. 6. Electrical current is defined as the movement of electrons through a conductor

of Electromagnetic induction [1](“Faraday’s Law‚ discovered in 1831 by Michael Faraday‚ states that the induced electromotive force in a closed circuit is equal to the time rate of change of the magnetic flux through the circuit. Under Faraday’s Law‚ electric current is induced only if either the magnetic field is changing or the conductor is moving. Generators‚ for example‚ spin a coil of wire around a magnet to produce a steady current” [3]) did electricity become viable for use in technology. Since
