Hope the Portal will consider my suggestions. From Wikipedia, the free encyclopedia.

The IV curve of a non-ohmic device purple. However in some case it could be improved with presenting more practical data, links, etc which are considered in daily routine design for electrical engineers. The electrical resistance of an electrical conductor is a measure of the formjla to pass an electric current through that conductor. Dear Sir, I am a Job Seeker.

First of all I must say thanks to EE Portal Team for dedicated services providing to engineering community and to all without difference and updating the Engineering Professionals with the latest information of Electrical Engineering. One way and two-way slabs, isolated footings. Properties, Advantages and uses of concrete, cement aggregates, electrifal importance of water quality, water cement ratio, workability, mix design, storage, batching, mixing, placement, compaction, finishing and curing of concrete, quality control of concrete, hot weather and cold weather concreting, repair and maintenance of concrete structures.

Thanks a ton for the invaluable notes and deep insight into downloas conceptual basics. This is an excellent website! In some cases, however, the effect is put to good use.

Your works are totally awesome. Dynamics of ideal fluids: Do you have calculation for auto transformer winding sizing reduced voltage motor starter thank you. Resistance thermometers and thermistors are generally used in two ways. In the same way, a long, thin copper wire has higher resistance lower conductance than a short, thick copper wire. Similarly, electrons can flow freely and easily donload a copper wire, but cannot flow as easily through a steel wire of the same shape and size, and they essentially cannot flow at all through an insulator like rubberregardless of its shape.

The resistance of a filament is temperature-dependent; these values are for when the filament is already heated up and the light is already glowing. I need a curve where the first drop is at A in 5 sec, the second is at A in 2 sec a third one at 10 A in 0.

Simple ohmmeters cannot measure low resistances accurately because the resistance of their measuring leads causes a voltage drop that interferes with the measurement, so more accurate devices use four-terminal sensing. These are called nonlinear or nonohmic.

Definition of the flood, causes, and effects, methods of flood control, water logging, preventive measure. Complex numbers are used to keep track of both the phase and magnitude of current and voltage:. In the hydraulic analogycurrent flowing through a wire or resistor is like water flowing through a pipe, and the voltage drop across the wire is like the pressure drop that pushes water through the pipe.

Was feeling how i missed all these days. Air standard Cycles for IC engines: Electrical resistivities of the elements data page and Electrical resistivity and conductivity. More information at http: Reinforced brickworks, columns, staircases, retaining wall, water tanks RCC design questions may be based on both Limit State and Working Stress methods.

Thanks a lot, Sergiu. Land reclamation, Characteristics of affecting the fertility of soils, purposes, methods, description of formuls and reclamation processes. For example, in an ideal resistor, the moment when the voltage reaches its maximum, the current also reaches its maximum current and voltage are oscillating in phase.

If these pressures are equal, no water flows. A resistance thermometer is made of metal, usually platinum, while a thermistor is made of ceramic or polymer. Measurement of frequency and phase angle. Resistors, on the other hand, are made of a wide variety of materials depending on factors such as the desired resistance, amount of energy that it needs to dissipate, precision, and costs.

Thank you for information. I have never seen any website like as your website. The temperature coefficient of resistivity is similar but not identical to the temperature coefficient of resistance.

For the term used when referring to touchscreens, see resistive touchscreen. Great website with useful and informative resources. Thanks Edvard, this is a great site to be at. Some resistors, particularly those made from semiconductorsexhibit photoconductivitymeaning that their resistance changes when light is shining on them.
