ABSTRACT Typically Electronics Has Been Defined In Terms Of Three Fundamental Elements Such As Resistors‚ Capacitors And Inductors. These Three Elements Are Used To Define The Four Fundamental Circuit Variables Which Are Electric Current‚ Voltage‚ Charge And Magnetic Flux. Resistors Are Used To Relate Current To Voltage‚ Capacitors To Relate Voltage To Charge‚ And Inductors To Relate Current To Magnetic Flux‚ But There Was No Element Which Could Relate Charge To Magnetic Flux. To Overcome

ELECTROMAGNETIC INDUCTION Electromagnetic induction is the production of an electromotive force across a conductor when it is exposed to a varying magnetic field. It is described mathematically by Faraday’s law of induction‚ named after Michael Faraday who is generally credited with the discovery of induction in 1831. Electromagnetic induction was discovered independently by Michael Faraday and Joseph Henry in 1831; however‚ Faraday was the first to publish the results of his experiments.[4][5] In

circuit and recording measurements of the voltages across a 218Ω or 331Ω resistor‚ and a 0.470 μF capacitor while varying the frequency between 802 Hz and 602 Hz. With the recorded voltages we can determine the voltages across the 79.5 mH inductor‚ and the inductors resistance of 205Ω. With all four recorded measurements we can find the experimental voltage of the LRC circuit with the equation V = ((VL – VC)2 + (VR + Vr)2)1/2. The recorded experimental voltages acquired a percent

Kumar Department of Electrical Engineering‚ Indian Institute of Technology‚ Madras 600 036‚ India Received 19 March 1995; revised 10 May 1996 Abstract A microcontroller based scheme for LCR measurement is described. The unknown element (an inductor or a capacitor or a resistor) is measured employing a non conventional ac bridge. The element to be measured forms one arm (side) of the bridge and the second (series) arm is made up of a simple resistor. A Multiplier type Digital to Analog Converter

Nebulizer A nebulizer is a device that is used for breathing treatments such as asthma‚ cystic fibrosis‚ and other respiratory illnesses. It changes liquid medicine into an aerosol. Aerosol is a "mixture of gas and liquid particles‚" and the best example of a naturally occurring aerosol is mist‚ formed when small vaporized water particles mixed with hot ambient air are cooled down and condense into a fine cloud of visible airborne water droplets.

WIRELESS POWER TRANSFER ABSTRACT The main objective of this project is to develop a device for wireless power transfer. The concept of wireless power transfer was realized by Nikolas tesla. Wireless power transfer can make a remarkable change in the field of the electrical engineering which eliminates the use conventional copper cables and current carrying wires. Based on this concept‚ the project is developed to transfer power within a small range. This project can be used for charging

the current and convert it to thermal energy. The second is that the current through the inductor will result in a magnetic field. However‚ since the current is transient (not constant)‚ the magnetic flux through the inductor is not constant‚ resulting in an emf across the inductor‚ pointing in the opposite direction of the voltage across the capacitor. Once the capacitor is discharged‚ the emf in the inductor‚ in trying to prevent the change in magnetic flux‚ will result in a current in the opposite

This suggests that part of our results were very accurate (series parallel RC network) and the rest of our results were severely affected by the interference and resistance of the inductor. Overall‚ all measurements were carefully and accurately made‚ however there were uncontrollable factors that need to be considered.

fluorescent light isn’t controlled‚ it can blow out the various electrical components. A fluorescent lamp’s ballast works to control this. The simplest sort of ballast‚ generally referred to as amagnetic ballast‚ works something like an inductor. A basic inductor consists of a coil of wire in a circuit‚ which may be wound around a piece of metal. If you’ve read How Electromagnets Work‚ you know that when you send electrical current through a wire‚ it generates a magnetic field. Positioning the
